I don't want to make myself a target, because I'm just as imperfect as everyone else, but I have always liked celebrities who first focus on being good people.
I think it's desperately hard, and there are pressures I can't understand when you get to a certain level of celebrity, but that has to be the goal. Through everything I do, I try (and frequently fail) to put my behavior first, accomplishment second.
He definitely brought some of the pressure on himself by being a media darling, and I have really hated his cutesy crap from the minute he came out (his comments about how so many great guitarists have never made teenage girls cry made me want to vomit). His words do matter. I don't overlook that, but I know that we all have low points in life.
Hopefully he can make a real change in his life, not just the appearance of one for PR reasons.
