A lot of what inspired many musicians is celebrating differences, and people relate to that - more people feel like the unpopular, freaky one than the one in the in-crowd.

The NHS is a bit iffy when you sprain an ankle, but when it's a high-priority issue, it's fantastic. They don't mess about. They're incredibly efficient when things go wrong.

I learned to stand up for myself at school where I was never too popular.

I started my music career at 18 and for a long while I let other people handle my affairs.

I tasted huge success with my first album, and when it's happening it feels like a roller coaster you can't get off. You should be very careful about wishing for success on that scale.

I get really frustrated if people don't smile.

Also, I think women really come into their own in their 30s.
