Most investors are obsessed with the market size today and they don't think about how the market is going to evolve.

By the way, that's my number one piece of advice if you're going to join a startup: pick a rocket ship.

One of the great and terrible things about starting a start up is that you get no credit for trying.

At YC we have this public phrase, and it's relentlessly resourceful.

If you compromise and hire someone mediocre you will always regret it.

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.

The natural state of a start-up is to die; most start-ups require multiple miracles in their early days to escape this fate.
