The team you build is the company you build.
The real thing you do is you ask a lot of questions.
I think you must have your own office. I don't believe ever in shared office spaces.
Don't accept the excuse of complexity. A lot of people will tell you, this is too challenging, this is too complicated, yeah well I know other people simplify but that's not for me, this is a complicated business. They're wrong. You can change the world in 140 characters.
Treat customer support as a product.
It's actually a good thing if you do reference checks on somebody and half the people you call say they are a micromanager and the other half say they actually give me a lot of responsibility. That's a feature not a bug.
