This is a good less-than-four-minute reminder of Five Solid Startup Lessons, taken from Stanford’s Entrepreneurship Corner. The speaker is Aaron Levie, who founded Box.net from his dorm room.
The five lessons, by the way, are:
1) Do something that was not possible three years ago,
2) Do something you are extremely passionate about,
3) Don’t compromise,
4) If you feel comfortable, you’re probably not doing it right, and
5) Don’t write your obituary too early.
