There are 3 things I look for when I hire people. Are they smart? Do they get things done? Do I want to spend a lot of time around them?

Be suspicious of any work that is not building product or getting customers. It's easy to get sucked into an infrastructure rewrite death spiral.

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.

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

Whatever the founder cares about, whatever the founders think are the key goals, that's going to be what the whole company focusses on.

If it works out, you're going to be working on this for 10 years.

If you pivot, do it fully and with conviction. The worst thing is to try to do a bit of the old and the new-it's hard to kill your babies.
