PSA: If you're starting a company and you haven't watched the YC startup class videos, you should.

Or do what I did: download them as audio files onto your phone and listen to them on the go. I never felt I was missing much by not having visuals and it makes for great dog-walking material.

The videos are here: http://startupclass.samaltman.com/

You really should watch them all, the quality varies a little from very good to great.
