I've talked to hundreds of people who have graduated from high school over the years and not one of them...not a single one, has ever said to me "I'm glad I quit". Doesn't matter what the reason was at the time or what sport it was: wrestling, football, track, whatever. No one ever says " I'm glad I didn't go out, Quitting that sport was the best thing I ever did". No matter how painful things are at the time it never matches the pain or longevity of regret.
