I don't want to know the answer honestly, it's just too depressing. I follow football recruiting a lot closer and if you consider how many 5 Stars or amazingly talented guys that just throw it all away it's just sad. A lot of it is many of those guys come from rough backgrounds with little support and lots of people looking to take advantage of them. They just don't role models to show them how to live responsibly or to teach them that you have to work hard to succeed.
Still, in the end every person is responsible for themselves. There are plenty of folks who came from nothing to be uber successful and there are plenty who had every advantage and the best parents but ended up as scumbags. Life is about choices and in the end people have to understand that every choice has consequences for good and for bad but learning to own your choices is the key to success and happiness.
