When I decided to write a book about my life I thought I'd have to make loads of stuff up. I mean, who wants to read about someone like me? But as soon as I started writing, the weirdest thing happened. I found out I wasn't who I thought I was. And I stopped being scared. Best of all, I discovered that when you finally decide to be brave it's like waving a wand over your life - the most magical things can happen.
