Thanks to Matt for passing this along. It reminds me of something Mohnish Pabrai talked about at the Pabrai Funds Annual Meeting this past weekend. He mentioned that studies show that the brain is developing quickly between the ages of 12 and 19, and that this is a time when kids should be beginning to specialize in something and really start pursing their interests, and yet our education system is rarely set up this way. He mentioned Warren Buffett (among others) as an example of someone who had gotten an early start on his passion around those ages and went on to become successful as he learned valuable lessons and got that spark during those important times. In Buffett’s case, he was doing things like renting out pinball machines and a Rolls Royce, among other ventures.
