At school there was an annual school disco and I'd be standing in my bedroom wondering what to wear for hours on end. Eventually I'd arrive at a decision that was just the most ridiculous costume you could have ever devised - I think it was probably knitted Christmas jumpers on top of buttoned-up white shirts.
Generalised anger and frustration is something that gets you in the studio and gets you to work - though it's not necessarily evident in anything that's finished.
