Education/Knowledge. Simply! it's education. Because Education is one of the major thing that money can buy. As everybody usually believed, no one could ever be defeated if you have the brain to win the reality. Well in fact, I'm don't underestimate the people who haven't finished their studies. But I'm saying that if you have the brain or simply the knowledge in dealing anything. That would probably the reason why money can't buy you. :-) ... correct me if I somewhat stated wrong details. :-)
