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

Every first time founder waits too long, everyone hopes that an employee will turn around. But the right answer is to fire fast.

So always keep momentum, it's this prime directive for managing a startup.

Everyone starting a startup for the first time is scared, and everyone feels like a bit of an imposter.

We talk to a team they've gotten new things done, that's the best predictor we have that a company will be successful.

You really want to know your cofounders for a while, ideally years.

The tenth social network, and limited only to college students with no money, also terrible. Myspace had won.
