Bjorn Ulvaeus

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 like people who don't accept boundaries. Like Florence Nightingale. And Napoleon or Louis XIV, though I'm not sure how much I'd have liked to meet them. I admire people who aren't circumscribed by circumstance.

Listen to the Beatles' 'Things We Said Today.' Ringo Starr does not play a fill in the entire song. It doesn't need it. 'A Day In the Life' has gorgeous fills, but there, the song needs it. When I play on any record, I'm striving to get where Ringo is. You play what doesn't take you out of the song.

If I'm not barefoot, you'll probably find me with a pair of New Balance on. And I'm not one of those hipster-jump-on-the-band-wagon-ironically-cool NB fans. I've been rocking those kicks since they were true nerd shoes. Since the '80s, yo! Word.
