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 wish I could learn that just three drinks is enough, but I have not learned that.

I have a rule for working out if the root problem of something is, in fact, sexism. And it is this: asking 'Are the boys doing it? Are the boys having to worry about this stuff? Are the boys the centre of a gigantic global debate on this subject?

But nearly every woman I know has a roughly similar story - in fact, dozens of them: stories about being obsessed with a celebrity, work colleague or someone they vaguely knew for years; living in a parallel world in their head; conjuring up endless plots and scenarios for this thing that never actually happened.

But deciding not to have children is a very, very hard decision for a woman to make: the atmosphere is worryingly inconducive to saying, "I choose not to," or "it all sounds a bit vile, tbh." We call these women "selfish" The inference of the word "childless" is negative: one of lack, and loss. We think of nonmothers as rangy lone wolves - rattling around, as dangerous as teenage boys or men. We make women feel that their narrative has ground to a halt in their thirities if they don't "finish things" properly and have children.

When Rudy Giuliani became mayor of New York in 1993, his belief in the 'Broken Windows' theory led him to implement the 'Zero Tolerance' crime policy. Crime dropped dramatically, significantly, and continued to for the next ten years. Personally, I feel the time has come for women to introduce their own Zero Tolerance policy on the Broken Windows issues in our lives - I want a Zero Tolerance policy on 'All The Patriarchal Bullshit'.

You can always tell when a woman is with the wrong man, because she has so much to say about the fact that nothing's happening.
