You're either not hiring at all or it's probably your single biggest block of time.

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

Remember that the idea will expand, and become more ambitious as you go.

Aim to be the best in the world at whatever you do professionally. Even if you miss, you'll probably end up in a pretty good place.

Be suspicious of any work that is not building product or getting customers.

Two other things that we hear again and again from our founders, they wish they had done earlier, and that is... simply writing down how you do things and why you do things.

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