7 things everyone should do while they’re in college that can help them in the future
Here are the must-dos that you need to check off your list before you get your diploma, from entrepreneur Liz Wessel.
Here are the must-dos that you need to check off your list before you get your diploma, from entrepreneur Liz Wessel.
This post is part of TED’s “How to Be a Better Human” series, each of which contains a piece of helpful advice from someone in the TED community; browse through all the posts here.
For those fortunate enough to be able to go, college can feel limitless — full of endless quantities of new people, new ideas, new experiences, and new possibilities. This abundance can be enough to make students lose sight of a hard fact: College isn’t forever. That’s why Liz Wessel, entrepreneur and founder of Way Up, a US-based job site for college students and recent grads, wants people to seize all of those opportunities now — before graduation.
“I have too many friends who have graduated from school after spending hundreds of thousands of dollars on their education, after spending four years of their life, if not more … and then they come and they tell me how much they regret not doing something [during college],” says Wessel in a TEDxRutgers talk. To prevent you from feeling those future pangs, she shares the 7 things she thinks every student should do before they leave campus for good.
1. Send out cold emails (even if you don’t want to).
Think about someone you’d really like to meet — maybe it’s a distinguished alumna of your college, a writer whose work has changed your outlook, or a person who is a pioneer in an industry you’re curious about. Then, find their email address (“there are a million tricks and hacks on how to do it online,” says Wessel), and start a conversation with them.
It worked for Wessel. By the end of her senior year at the University of Pennsylvania, she had two job offers: one was to be a product marketing manager at Google, and the other was for a position at a venture capital fund. Both positions seemed great, but Wessel was torn. While she wasn’t quite sure what either role entailed, she did know that she wanted to start a company within a few years after graduation. So she emailed a venture capitalist, told him she was a student at Penn and trying to figure out her life, and explained her dilemma. He replied and told her if she wanted to start a business some day, she should take the job at Google.
Why you should do this while you’re still in college:
For many people, sending out cold emails can be awkward, uncomfortable, maybe even an exercise in rejection. But one major reason to look beyond your doubts and do it anyway is because you’re still a student. As Wessel puts it, “Everyone in the world wants to help college students, so please use that to your advantage.”
But do not bury this advantage deep in your email. Wessel adds, “In your first sentence in your cold email, you should be saying, ‘Hi, my name is ___ and I’m a college student at ___ .’” And if there’s any other connection you share with the person — they went to the same elementary school as you, volunteer for the same cause, support the same sports team — mention that up front, too.
2. Find your five.
Wessell credits her present success to the people she met when she was in college: “I would not be where I am today at all had I not made the friends that I made.”
Her recommendation:“Befriend five people who you would bet on … If you’re truly friends after you graduate, they’re gonna help you and you’re gonna help them.”By “bet on,” this doesn’t mean they must all be future-Time-magazine-cover material; rather, they’re people you like and admire and seem to be on a trajectory to make their mark on the world. Through your life, they’ll also serve as your personal board of directors, or legion of superheroes, as coach and consultant Tania Katan puts it.
Why you should do this while you’re still in college:
Wessel says, “There’s never going to be a time again where there are going to be … thousandsof brilliant minds around you, learning alongside you, except when you’re in college.”
3. Take a class that teaches a practical skill.
While Wessell truly enjoyed studying the subjects she majored and minored in — political science, Japanese and math — one elective she took has proven to be surprisingly beneficial. She says, “That one graphic design class has helped me in my day-to-day life more than all of my other classes combined.”
For Wessell’s WayUp cofounder, it was a negotiation class he took in college. Now, she says, “he’s the guy who negotiates when we get term sheets from venture capital funds.”
Why you should do this while you’re still in college:
Even if your first job aligns perfectly with your major, the working world will inevitably call on other parts of you. That’s why it’s smart to acquire a skill or skills — such as the ones just mentioned — that will provide you with tools and a perspective which you can apply to a variety of fields. “If you take one class in a very practical skill, whether it’s a computer science class, a negotiation class, or a writing class, it will pay off dividends,” says Wessel.
4. Start something.
Wessell realized she was an entrepreneur in college, and she doubts she would have started WayUp if she hadn’t launched a business as an undergrad when she was 19.There are so many kinds of things you can start — while it could be a business, it might be an extracurricular club, a publication, a public-service drive or campaign, a film series, a TEDx event (apply here), or anything else you can dream up.
Why you should do this while you’re still in college:
Conceiving of a venture, bringing it into reality, and keeping it going will provide you with an education like no other. It also preps you for future jobs, no matter what they may be. “Once you get into the real world of work, you’re going to see that executing projects is pretty much all you do, and it’s really hard,” says Wessel. “It’s great to get that experience during college.”
Similar to cold emailing, college students have a tremendous built-in advantage here. Says Wessel, “corporate sponsors are way more willing to help you when you say you’re a student and this is a university project … versus you’re just another recent grad.” Plus, on campus, there are professors, deans and staff to advise you, competitions and grants to earn seed money, peers who’d like to collaborate, and auditoriums, offices, conference rooms and other facilities to use. Make use of all these resources while you can.
5. Find the professor.
“Everyone’s ‘the professor’ is different,” Wessell says. How to identify them: They’re the one who teaches the class that sets your mind on fire (in a good way), conducts research in the precise area that you’re passionate about, or sees the world in such a distinctive way that you can know you can learn from them.
When she was at Penn, Wessell was determined to study with a particular expert in entrepreneurship — only to learn that undergrads couldn’t take his courses. She kept showing up at the professor’s office until she was finally granted permission. He later helped Wessel with a business plan, which provided the foundation for WayUp, and they’ve stayed in touch. “I can safely say that professor changed my life,” she says.
Why you should do this while you’re still in college:
It’s so much easier to find the professor when you’re at college — and much harder after.
6. Go on an adventure.
While there are many great things about life after college, vacations aren’t usually one of them — at least not for entry-level employees. Unless you’re a teacher or get a job in education, Wessel says, “there’s no such thing as spring or summer break. There’s barely a winter break.”
One summer during college, Wessel had a marketing internship in Tokyo and it made her realize that she wanted to work abroad sometime after graduation. Thanks to the experience, she eventually led a brand team in India for Google.
Why you should do this while you’re still in college:
“You’re never going to have the opportunity [later in life] to just be carefree,” explains Wessel. Take the time while you’re in college — even if it’s for a week in summer — to have a completely new experience. She says, “Figure out where’s your comfort zone. Do you like being out of your comfort zone? Or do you like being in it? What do you enjoy doing?” Get a job abroad, go on a road trip, take a workshop or class at another college or school.
7. Get as much work experience as possible.
Although Wessell suggests logging as many on-the-job hours as possible, she cautions, “I don’t mean [that you should] have one internship you do every single summer, or [that you should] be a camp counselor every single summer, or be a receptionist at the local dentist every weekend.” Instead, try out as many different kinds of work experiences as you can.
Why you should do this while you’re still in college:
It’s a time when you can job-hop without looking unreliable or flaky. “During college, you’re totally OK to have a new internship every summer; you’re totally OK to have a job every year of college, maybe even every semester,” Wessel says. “When you graduate from college, if you have a new job every six months, that looks really bad.”
Doing a variety of jobs is the best way for you to figure out what you want to do after college — and, just as important, what you don’t want to do. Wessel explains, “This is the time you should figure out what you love doing, what you hate doing, what you’re good at, what you’re bad at.”

How to build a better business model by blockchain
Abstract
At present, we are living in a world that the surroundings are changing dramatically every day. Since the blockchain has been invented, it already self-upgraded three versions (Spithoven, 2019). Blockchain has been treated as a technological invention that can change the world, the main features include cryptography and cybersecurity. Many companies already used it to deploy their new business model in many different fields (Zhang, Xue & Liu, 2019). The security and privacy of blockchains which are shown by the current applications proved that this advanced technology can help with building a better model.
Introduction
Not far from now, on May 22, 2010, a programmer bought two large pizzas for 10,000 bitcoins. They were only worth about 30 dollars at the time (Wong, 2018). Now worth 80 million dollars, none of the companies have this rising price in the stock market like this.
Since the blockchain has been invented,11 years have passed. Nowadays almost everybody knows two words, blockchain and bitcoin. Recently, almost every central bank has announced it was in the process of developing their blockchain system and issuing their digital currency. Meanwhile, lots of technology companies are adding their blockchain departments (Paul & Michael, 2015). Not long ago when a company announced that it would use blockchain, the stock price would increase incredibly. Those scenes are familiar to the early stage of Internet mania. In order to avoid the collapse of the industry finance structure, knowing more about the blockchain is necessary. Blockchain technology is not omnipotent, it cannot point stone into gold. However, the advantages that blockchain shows include security and efficiency, which can help build a better business proved by some current models.
Blockchain
In this paper, the explanations are mostly focusing on the structure,technical characteristics and how to make use of them.
In a dynamic perspective blockchain is a database. It is a fixed-length infinitely expandable chain. Every transaction that takes place on the chain is recorded in block, the new block is the end of the old block (Joseph, Bambara & Paul,2018). Simply, try to imagine a scene where there is an office full of accountants, and there is a client depositing a check to his account. In the normal way there only needs to be one accountant to record it, and they only have one ledger which is the same operating principle as the old database (Steven, 2018). That flaw made it very vulnerable and easy to be altered or deleted. When it comes to blockchain, the rules are changed, every accountant needs to write it down simultaneously with security encryption method, so everybody knows how much clients have deposited but they don’t know who the client is unless the client wants them to know. If they want to change the client’s check, it can only happen when more than half of the accountants agree to change which makes it almost impossible to be altered (Huh & Kim, 2019).
However, blockchain is more than that, in this paper, it is referring to the combination of several technologies. The blockchain technology means a set of the data-structure, the algorithm, which easily established a security platform. With all those features blockchain can easily provide unbiased distributed P2P (peer to peer) network (Drescher,2017). This is the technology foundation of the security attribute.
Security
Based on the program foundation of the blockchain technology, when it comparing to the formal Internet, blockchain creates more security. First, talking about the protection of privacy as well as confidentiality, blockchain can do better than the Internet. For example, if a user wants to transfer 100 dollars to another user, users will need to provide lots of personal information and lots of setup procedures to complete this transaction but in blockchain the user only needs to use his own blockchain address which looks like a series of garbled number to another user’s address. Although this transaction will broadcast in the whole blockchain network, nobody will find out which address belongs to the user, and one user can own multiple addresses, which makes transactions almost anonymous. Second, blockchain can provide more integrity. This feature was mostly implemented by using hash algorithm (an algorithm that can automatically provide a crypto ‘signature’ for a text or a data file) (Veness, n.d.). The hash algorithm is the foundation stone of the blockchain. To alter the information which has hash signature, must crack the private key within the information first, this process means thousands of years decrypting. In that case, the cost to tamper the data in the blockchain is higher than on the Internet (Park, 2017). Last but not least, the usability is not like the Internet, if it’s main server break down the whole Internet will be influenced, even shut down because of this, but if the same situation happened in the blockchain, there is no such thing as a main server. Every user is a server so as long as the circumstances are not bad enough to make most of the user offline the blockchain will still working normally.
Based on the distributed ledger technology feature, blockchain not only provides security but also decreases the cost about companies’ system construction. With this feature, a new business model does not need a huge database anymore, because users’ devices are the company’s database. In that case, the blockchain saves a lot of money from the business database implementation fee, which not only includes the establishment fee but also with the maintenance charges (Aaron, 2018).
Efficiency
The efficiency that blockchain provides is mostly based on the smart contract technology. To imply this feature, a Russian genius teen created a platform built on blockchain called Ethereum. Ethereum is a special platform for smart contracts, the transit data between the terminals can be variables. Which means the data no longer need to be fixed before transmitting. Because of this property this platform can use to program the condition-orient application (Temte & Morgan, 2019). More specifically, within the smart contract the blockchain application can provide real-time updates without any manual control once the contract has been set, which means that it will execute itself automatically. In that case, it performed more efficiently than many interactions with the Internet in the same conditions. In the internet condition, only fixed information can be transmitting, to update the information need to transmit request back and forth several times. In blockchain the transmitting information can be variables, this feature cut off all the useless interactions between terminals instantly. Beyond that, it also can save a huge cost taken by the third parties or human mistakes (Rosic, Andonov & Mihaylov, 2019), besides the transactions between each endpoint.
No system is perfect. Blockchain also has some drawbacks but compared to the Internet in some fields, blockchain shows more advantages. With these two features, once customers experience the services provided by blockchain they will abandon the old system sooner or later (Kaye, 2018).
The previous paragraphs have conferred the advantages of blockchain, also show the reason blockchain is used to build the business model. However, the model does not appear out of nowhere. In the following paragraphs are some examples of the blockchain model.
Current examples
According to a research report release from the International Data Corporation (IDC), The blockchain market was expanded dramatically and is about to reach 12 billion USD before 2022(Wester, Close, D’Alfonso, Little& Xue, 2019). Many visionary companies’ CEO already acted within their companies. Some models they established begin to change the rules of current market.
Eastman Kodak is an old camera company. Influenced by the raising of the smartphone and the high quality of the camera planted on the phones, the company almost went bankrupt. By using blockchain technology they created a new platform called KODAKOne. This management platform is focusing on the copyright ownership. Users can put their portfolio on the platform. With the character of blockchain, the pictures are protected automatically and every view and click gets paid (Ratko, 2019).
Deloitte has been involved with blockchain for many years. Their blockchain platform named Rubix in 2014, was called it a “one-stop blockchain software platform”. The platform provides three main functions, to improve Deloitte and its client’s performance in the advanced technology field, to investigate how to help the current service of business model by using blockchain, and probe how to use blockchain solve future problems (Nicola, 2015). With that it can help the company and its customers make better strategies.
Securitize is a startup company that enables the issuance and management digital securities, besides unlocking liquidity in the huge private securities market with compliant and easily tradable assets. Moreover, its platform can provide security tokens on public blockchains and make the compliance accurate at the token level (Vanessa, 2018). To make the assets tokenize is become a trend for wealth people to preserve their value.
As many pioneers of many industries already taken actions to implant the blockchain technology. There are many technology application scenarios were proved feasible. Based on that, imitate their successful examples can help build the better profitable business model. Moreover, this provide a chance to stand on the shoulders of giants. Different from explore the new territory, this is a path to expand more.
Conclusion
In the end although this paper did not come up with the business model by using blockchain. But it showed the path and the method by presented technology advantages such as privacy and security, along with current useful example models. Nowadays technologies have been changing with each passing day. Every technological change reconstitutes our life dramatically, for the sake of not been eliminated by the technology wave. We need to understand the blockchain further, not just limited in security and efficiency. There will be more advantages discovered in the future. Due to the limited space, this paper only showed a small part of what blockchain is capable of. To discover more, stay foolish stay hungry.
