There's a grace period where being a mess is charming and interesting, and then I think when you hit around 27, it stops being charming and interesting, and it starts being kind of pathological, and you have to find a new way of life. Otherwise, you're going to be in a place where the rest of your peers have been moving on, and you're stuck.
When you write something you know, you're making a story that will work, whether or not there's bits taken. It's always funny to me when people say, 'Well, it's clearly autobiographical,' and I say, 'Well, how do you know my autobiography?' Certainly, there are things that are connected, but I just think it's a very interesting assumption.
