If I wasn't dyslexic, I probably wouldn't have won the Games. If I had been a better reader, then that would have come easily, sports would have come easily... and I never would have realized that the way you get ahead in life is hard work.
I could have started a for-profit, venture-backed business that has a good spirit, and I think there are many of them - Google for instance. Maybe I could reach a billion people. That is high impact, but what happens in 50 years?
