Start-ups should be based on radical ideas. There should be a high failure rate for start-ups, because if there isn't their ideas aren't bold enough.

I enjoy not being a public company.

In a startup, absolutely nothing happens unless you make it happen.

I always had the old-school model that I'm going to work for as long as I'm relevant and focus on for-profit activities and someday when I retire I'm going to learn about philanthropy.

An awful lot of successful technology companies ended up being in a slightly different market than they started out in. Microsoft started with programming tools, but came out with an operating system. Oracle started doing contracts for the CIA. AOL started out as an online video gaming network.

Innovation doesn't come from the big company. It never has and never will. Innovation is something new that looks crazy at first glance. It comes from the 19-year-olds and the start-ups that no one's heard of.

The most important thing is to get on the right horse.
