I've been asked before, "Who are your heroes?" and these types of questions. I always find it hard to identify a single person or a single book or this sort of thing. I've always been forward looking. I was raised with the notion that you can do pretty much anything you want. You're able to accomplish anything you set out to accomplish. I was given a sense of confidence and I never really felt the need to - or I've never had the benefit, I should probably say - of being inspired by outside heroes.

You’re able to accomplish anything you set out to accomplish.

You should pursue your passion. If you're passionate about something and you work hard, then I think you will be successful.

You’ll fail at some things, that’s a learning experience that you need so that you can take that on to the next experience... What you learn from those challenges and those failures are what will get you past the next ones... I was the pretty consistent bull and the cheerleader on eBay actually.

It is not really work if you are having fun.

In the same way that you're driven in your business to keep innovating - Facebook is a wonderful example of constant innovation - think about doing that in philanthropy.

I built a system simple enough to sustain itself.
