It could be seen as narcissistic to have your own museum, but for me, it's such a long time ago - I have perspective. That young man in the funny clothes - he's almost a stranger, so I can tell his story.

Mostly, in song writing, my experience is that there isn't so much inspiration as hard work. You sit there for hours, days and weeks with a guitar and piano until something good comes. But the urge to write is something you have to have. A conviction, an ambition to write and never stop until you think, 'This is the best I can do.'

You make your first album, you make some money, and you feel like you still have to show face, like 'I still go to the projects.' I'm like, why? Your job is to inspire people from your neighborhood to get out. You grew up there. What makes you think it's so cool?
