Edge, don't confuse burnout with sore losers. Hingis was a primadonna, and incidently quite when she actually had hungry competition. I am glad that whole brat pack is getting the quitter bug. To the quitters, cheers! I have noticed that most introverts that quite after success see the future very clearly, and when the surprises are over they find another means to entertain themselves. Hell is repetition. Once an intelligent introvert sees that in the given activity, it is usually over. Federer may quite inside of 5 years depending on the rest of the tours ability to adapt. I think he is getting a kick out of watching these guys squirm right now, but I think it may get old sooner than most expect. I believe he may be at a mental level that few people ever achieve. Borg may be the only one in the history of tennis that shares the same mindset as Federer. For now, I will just enjoy him beating up on some of those idiots like Roddick, Hewitt, Blake, and Philippoussis.
