Are there any child stars who have made it out of their 20's without some serious psychological and emotional scarring?

I still blame this kid's parents. Either they pushed him, or they weren't keeping a close eye when he was doing this:

Those videos might surprise some who think this kid is just aother pretty face. I wish I could play drums like he did at 9 years old!

They probably hoped for some kind of fame, but it seems like that always comes at some sort of price.
