A lot of people – and I’m just not one of them – believe that you should live for the now. I think what you do is think about the great expanse of time ahead of you and try to make sure that you’re planning for that in a way that’s going to leave you ultimately satisfied. This is the way it works for me.

Life's too short to hang out with people who aren't resourceful.

Am I going to regret leaving Wall Street? No. Will I regret missing the beginning of the Internet? Yes.

I don't think that you can invent on behalf of customers unless you're willing to think long-term, because a lot of invention doesn't work. If you're going to invent, it means you're going to experiment, and if you're going to experiment, you're going to fail, and if you're going to fail, you have to think long term.

Any business plan won't survive its first encounter with reality. The reality will always be different. It will never be the plan.

If you don't understand the details of your business you are going to fail.

The most important single thing is to focus obsessively on the customer. Our goal is to be earth's most customer-centric company.
