I've been good at product entrepreneuring.

The first rule (of investing) for me is don't have rules. You find one amazing investment and that's all that matters. If you pick the right body of water, you might not need a boat.

You can manage 50 people through the strength of your personality and lack of sleep. You can touch them all in a week and make sure they're all pointed in the right direction.

From the beginning... I wanted to build a company that could sustain not for two years or four years or even ten years but be something that really matters over time the way Amazon and Google and others have.

My approach is that you have to earn the respect of people you work with.

Get five or six of your smartest friends in a room and ask them to rate your idea.

I got involved early on in social media - I created one of the first social networks - and for me, social gaming was a natural evolution of that.
