I am who I am because of that messed-up childhood.

Every time I got drunk and out of order. Especially in my teens and 20s.

All of my hairstyles from the age of 16 to 25.

I would never have gone on a diet. I would go back with the knowledge that not being perfect is fine.

Ten more closets: I am a hoarder.

How little money really changes things. It buys doctors but not health, clothes but not taste, makeup but not beauty. When I was young and didn’t have anything, I imagined money had more power.

There are a few. As far as getting started, lots of people who really want to make a song have figured that out already. I very rarely get asked for advice from people who have never written a song and want to know how to get started. It’s usually about getting stuck or feeling like they’ve painted themselves into a corner. I remember getting asked a question from this one kid who was probably 13 years old. He wanted to know if it was okay to always write in A minor. He liked writing classical piano pieces and his favorite key was A minor. My favorite key is also A minor, so he wanted to know if that was okay.

An astronaut, a writer, a dancer.

The most extravagant thing was a bottle of 1904 armagnac for $1,000. I spent $10,000 on a Martin guitar in the 90s. I also spent $100,000 on a Fairlight keyboard and I ended up giving it away. Oh well.

A death threat at Glastonbury festival in 1989. The police told me not to go on, but I said I had to because I was headlining. So I wore a bullet-proof vest. It seemed unlikely that I would be assassinated, but it was shocking and very stressful.
