When you talk to a young teenage girl, they're just full of self-loathing. The reason they feel self-loathing is they don't feel normal. It is a world that has not been built for them. It's been built for men, and that's why they feel bad.

I always give three pieces of advice to all the teenage girls when I do my talks: long country walks - it's important to get some fresh air in your lungs, and be in contact with your body; masturbation - it takes the edge off, it'll get you through; and the revolution - believing in changing the world.

I told my girls, 'Look at Rihanna: She's one of the biggest pop stars in the world. She's really famous, really powerful, really rich. Yet in every single video she can only wear panties. Poor Rhianna! We'll know when she is properly powerful and successful when we see her in a lovely cardigan.'

Watching 'Girls' has just given me renewed courage.

If anyone was going to write a song or, you know, or a book, or make a film about a girl like me, it was going to have to be a girl like me, and quite literally, me.

Feminism means something - legislation, cultural change - but 'Girl Power' meant nothing more than being friends with your friends.
