No matter what you choose, build stuff and be around smart people.

You need conviction in your own beliefs, and the willingness to ignore others naysaying.

You never want to be in a place where an employee has vested 3 out of the 4 years of stock and they start thinking about leaving.

You can create value with breakthrough innovation, incremental refinement, or complex coordination. Great companies often do two of these. The very best companies do all three.

You need this sort of a tailwind to make a startup successful.

A board member of mine used to say sales fix everything in a startup, and that is really true.

You can basically change everything in a startup but the market.
