If someone is difficult to talk to, if someone cannot communicate clearly, it's a real problem in terms of their likelihood to work out.

No matter what you choose, build stuff and be around smart people.

You have to let your team get all the credit for all the good stuff that happens, and you take responsibility for the bad stuff.

You also want people who are maniacally determined and that is slightly different than having a risk tolerant attitude.

In the early stage of a startup, hiring senior people is usually a mistake. You just want people that get stuff done.

A board member of mine used to say sales fix everything in a startup, and that is really true.

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?
