I've been an entrepreneur three times. I started three companies.

Every kid coming out of Harvard, every kid coming out of school now thinks he can be the next Mark Zuckerberg, and with these new technologies like cloud computing, he actually has a shot.

No one should expect building a new high-growth, software-powered company in an established industry to be easy. It's brutally difficult.

One of the advantages of moving quickly is if you do something wrong you can change it. What technologies tend to do is they tend to make a lot of mistakes... but then we go back and aggressively attack those mistakes - and fix them. And you usually recover pretty quickly.

An awful lot of successful technology companies ended up being in a slightly different market than they started out in.

I don't think objectively we are in a tech bubble when tech stocks are at a 30 year low.

Practically everyone is going to have a general purpose computer in their pocket, it's so easy to underestimate that, that has got to be the really, really big one.
