From my very first real fighting experience in Thailand, I saw that the best fighters were the most humble. But, much like jiu-jitsu, you start to see it's a "chicken or the egg" question. Is it that great fighters lose their ego? Or is it that you cannot become great unless you lose your ego? Your ego keeps you out of the zone? Guys who can naturally control big egos do better? "You have to live through it," Dr. Lardon said. "The eighteenth hole at the PGA West is all water up the left, and if you hit it there you don't have a job. When you're not at peace with that, then you're in trouble."
