Pay Pal's Peter Teal

You must hire people who are undiscovered talents. You cannot recruit people that are ready proven. The hardest part, afterwards, is to manage them. There's a skill and discipline in managing people that you know well and are friends. And it's very different than managing strangers. To be thoughtful and successful at the strategy, you have to be pretty clear eyed about your friend's strengths and weaknesses. And not every e can do that well.
