"Your Heart" by Steve Vai

I could tell you to 'play from the heart' but what the hell does that mean? It's easy to say, but it's a hard thing to understand. When you say 'play from the heart' you mean 'play from your OWN heart,' but what is in your own heart? To know your heart you have to know yourself; and to know yourself, you have to be yourself; and to be yourself you have to like yourself. This goes into all these realms of psychology, but this is what I think is important to a person's playing and the way he expresses himself.
