Did you know you would become as successful as you have? Hell, no. But you know what? You were prepared, baby.
You want your parents to say, "Hey, I'm proud of you." When you don't hear that, you learn to compensate. You say, "Hell, I don't need their approval. If I get my music right, I'll have everyone else's approval." I didn't understand it then, but I now know that's what happened to me.
