Thanks man, I write in the hopes that even one other person gets it and benefits, even if there are 100 like "G.A L.".
I hope I don't sound as if I have total regret, in fact I have benefitted immeasurably (for instance, having the humble pleasure of going on to coach several champion athletes), and I will always have the satisfaction that even though I never reached the heavens, I at least touched the sky on my abilities (went from 6:34 to 4:38 mile), where most people don't even bother to look up.
