College can teach you so much. But for some entrepreneurial types, working at a startup can be a real education.

Faced with something of a crisis of confidence during my sophomore year of college, I did what few of my fellow classmates would even remotely consider: I withdrew from school and took a job at a startup. Call me crazy, but I was struggling to understand the point of school when it seemed there was a much more exciting world beyond the boundaries of our landlocked campus.

I took a position as a technical trainee and account manager at a small mobile-display startup in Boston. From the beginning, this internship fueled my interest in entrepreneurship. But here are four specific lessons I learned:

1. You’ll always be young. You’ll always feel a little inexperienced and unsure. Tack on the risk of working at a startup and you're bound to get nervous at times. Would I even have a job for the full four-month internship? I’ll always remember what my father said to me the day I accepted the position: “You’re only 19 years old. What’s the worst that can happen?”

2. Embrace the work. I was given tasks I had no idea how to do and was left to figure it out on my own. It's not that my bosses wanted to watch me squirm. They just knew that I had the tools necessary to figure it out. Plus, the only other employees on staff besides myself were the two co-founders, so they were pretty busy. That autonomy and trust is what really helped me grow as an employee, a thinker and a leader.

3. Take whatever responsibilities you can get. There is no downside to this. At the very least, you will learn from the experience. Within a month I was on client calls, walking them through the user experience, answering questions and developing my own FAQ guide for the accounts I owned. I was attending events, sales meetings, running employee interviews and product roadmap meetings.

4. Remember to have fun. The startup's co-founders taught me that no one can get by without the occasional margarita night.

When I left to return to school, I was a completely different person. If society did not demand a degree, I would have stayed. I knew by then what it was like to be a part of something big. I knew what it meant to have a very small piece of an exponentially growing pie. And I knew that was a feeling I would never want to fade away.

Three months later, I started my own company: a fast-casual, sustainable salad and wrap restaurant about three miles from campus. It’s a little different from media analytics, but I'm still learning!
