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

The track record for founders that don't already know each other is really bad.

The best source by far for hiring is people that you already know and people that other employees in the company already know.

Just put a little pin in your mind: when you cross 50 employees, there are a new set of HR rules that you have to comply with.

Later, you should learn to hire fast and scale up the company, but in the early days the goal should be not to hire. Not to hire.

You can have a startup and one other thing, you can have a family, but you probably can't have many other things.

The startups that do well are the ones that are working all the time.
