"Searching for Bobby Fischer". Nobody has won all the national chess championships that Josh has. But even more impressive, when he turned 21, he took on the challenge of mastering something completely new and very different from chess: martial arts. He realized that he had learned how to grow and succeed, and he could apply that understanding to other domains. And so, he devoted himself relentlessly to tai chi chuan. And after lots of hard work, many failures, and some broken joints, he became a great martial artist, and he won two world championships.
