More insight from Malcolm Gladwell. Check out his discussion of Outliers [<a href="http://www.gladwell.com/outliers/index.html" rel="nofollow">http://www.gladwell.com/outliers/index.html</a>] too. Software entrepreneurs may find this interesting: "I actually have a lot of fun with birthdates in Outliers. Did you know that there's a magic year to be born if you want to be a software entrepreneur? And another magic year to be born if you want to be really rich? In fact, one nine year stretch turns out to have produced more Outliers than any other period in history. It's remarkable how many patterns you can find in the lives of successful people, when you look closely."
