This is a great video presentation (a little dated, 2001) by Frank Levinson of Finisar that has some great advice for start-ups.  In particular, get customers; then listen to them. There is other good advice too, like; Get a couch, you’ll be sleeping on it from time to time. Seriously though, storytelling from entrepreneurs is a great way to learn from people who have been there and made mistakes. If you like this kind of format, definitely check out the Entrepreneurs Unplugged series at CU-Boulder.

Thanks to Guy Kawasaki and Alltop for this find.
