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.

I think the best thing you can do is be aware that as a first time founder you are likely to be a very bad manager.

Firing people is one of the worst parts of running a company. Actually in my own experience, I think it is the worst.

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.

Because so few people make an actual long term commitment to what they're building, the ones that do have a huge advantage.

There's no way I know, to get through the pain of a startup without belief that the mission really matters.

If you don't love and believe in what you're building, you're likely to give up at some point along the way.
