I think there have been lots more sports superstars with self control than without, and losing self control doesn't do anything good for performance – just look at Tiger Woods for example.
Yeah, he has exemplary self control – just remind me how many women besides the one he made a life commitment to that he stuck his cock in…
I can honestly say that I've never in my life lashed out at anything through frustration. You worry me slightly!
I worry me slightly too! However, my wife likes to remind me that I've never even offered to hit her, the dog or anything remotely expensive, nor do I sleep around, lash out verbally at people, or bear grudges for years on end and let them eat away at me. I would say my passion is pretty well managed, given it's never brought to bear in a destructive way on any living being, human or otherwise.
