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.'

I can well imagine that certain writers, even writers that we'd consider today very great writers, may not necessarily have tested highly on IQ just because of their numerical skills, or maybe they may not be very good at memory, and are not particularly good at these kinds of tests.
