It's easy to move fast or be obsessed with quality, but the trick is you have to do both at a startup.

You can't be focussed without really great communication

I really believe that the single hardest thing in business is building a company that does repeatable innovation... and just has this ongoing culture of excellence as it grows.

Starting a business is like riding a wave between life and death. If you can hang on long enough, you're bound to succeed

Mediocre founders spend a lot of time talking about grand plans, but they never quite make a decision.

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.
