In general don't start a startup you're not willing to work on for ten years.

You never want to be in a place where an employee has vested 3 out of the 4 years of stock and they start thinking about leaving.

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

Every first time founder waits too long, everyone hopes that an employee will turn around. But the right answer is to fire fast.

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.

Every company has a rocky beginning.

Even though plans themselves are worthless, the exercise of planning is very valuable and totally missing in most startups today.
