Never love someone whom you think you need to mend – or who makes you feel like you should be mended. There are boys out there who look for shining girls; they will stand next to you and say quiet things in your ear that only you can hear and that will slowly drain the joy out of your heart. The books about vampires are true, baby. Drive a stake through their hearts and run away.

When you say you're not a feminist, if feminism hadn't existed, and you didn't live in a feminist world, you wouldn't be saying that, because you'd be too busy scrubbing out the toilets in back while cooking up your husband's tea and dying in childbirth at the age of 34.

If you come from a working-class background, you can't afford to write full time, because you're just not being paid. Basically, all my arguments come down to Marxist doctrine: The world is shaped by money, so the only voices you'll hear are the ones with money behind them. But thankfully, culture and cool are some things that circumvent money, because if you're cool, people will want to give you money - suddenly you shape the market and people start coming to you. Which is why culture has always been a traditional way out for working-class people.

Flyaway, problem hair is the enemy of feminism, and was probably invented by the Man to crush Susan Sontag.

There's something so free about being a fan and being enthusiastic about stuff - you attract all the other people who are also loving and enthusiastic when you're sending out signals of love. When you start to communicate cynicism and hatred, it leads you down a completely different path.

A 'sign of weakness' for a male celebrity is being found to be unfaithful, or unkind to an employee, or having crashed their car while stoned out of their tiny minds. A 'sign of weakness' for a woman, on the other hand, can be a single, unflattering picture.

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.
