Malcom Gladwell has a new book coming out in a couple of weeks called "Outliers".. He delves into all of this, I'm half way through it and I cant put it down. He has so much proof! Proof of all of the contributing factors that go into the exceptional accomplishments of certain extraordinary people. People like Bill Gates and Bill Joy. It's a little mean of me to mention the book as I think it gets released on the 18th, until I saw your post I resisted mentioning it.

The only answer I have for you is probably not what you are looking for- there is a Buddhist expression called "mu". It means you have to un-ask the question before we can proceed, your question is like saying "are you still beating your wife?" Of course, either way one answers is incorrect- if you say "no" it could mean you used to beat your wife, and if yes thats quite bad as well. The correct answer can only be mu. So, in essence, there are too many factors involved for a yes or no . Get the book and then email me if you would like, I'd love to chat about it, its fantastic!
