I joined the board of the Santa Fe Institute.

Having seen a non-market economy, I suddenly understood much better what I liked about a market economy.

The Internet is an incredible business tool. First of all, the Internet/the cell phone - the cell phone is just another way to get at it - I think is having a huge impact in Africa most particularly, where it enables people - suddenly, they know crop prices. They can communicate. It makes their lives more efficient.

No system in the world is so well-designed that it can't grow stale, rigid, or corrupted by those who benefit most from it.

It may not always be profitable at first for businesses to be online, but it is certainly going to be unprofitable not to be online.

I had a lot of successes, but what really made me fearless was my complete failure at Zidd-Davis. Once you've lived through that, you know you can survive, and you're not as scared... There's nothing to build confidence like real achievement, but also like real failure.

Always make new mistakes.
