Just another reason why he should've stayed in school! Closely supervised? Check. Win another national championship? Perhaps.
In all seriousness, I think it's probably tough to be 19, rich, and on your own. I don't know if I could've handled it. I agree, though, that he needs to take a long look at himself now before something really bad happens. He could easily get stabbed, shot, or end up in a serious accident.
I hope he turns it around soon.
"We are not provided with wisdom, we must discover it for ourselves, after a journey through the wilderness which no one else can take for us, an effort which no one can spare us, for our wisdom is the point of view from which we come at last to regard the world." --M. Proust
