He was called names, bullied, adults always say that there are things wrong about him and how his aspirations to be a famous rock star is impossible. But he didn't listen to them. He used all the pain they brought to him and used it to strive for his aspirations. And look at where he is now, he is very successful. And where are those people who treated him bad? They're living the shity life normal citizens live. :)
