If you're happy, that's probably the most important thing. Everyone probably has their own definition of success, for me it's happiness. Do I enjoy what I'm doing? Do I enjoy the people I'm with? Do I enjoy my life?

There's always an opportunity to make a difference

If you have to go through life being unhappy to conform to society around you, that's not a very good deal.

It had always made sense to me to build a business based on what people really wanted, rather than guess what we thought they might want.

If you look at innovation, it doesn't just occur in the lab.

People ask me all the time, 'How can I become a successful entrepreneur?' And I have to be honest: It's one of my least favorite questions, because if you're waiting for someone else's advice to become an entrepreneur, chances are you're not one.

Regrets are born of paths never taken.
