I've always subscribed to the notion that a writer always has something else to say, and the more you write, the more you have to write about, because the act of writing is self-generating.

When you're sixteen and struggling to forge an identity out of a morass of hormones and daydreams, remarks like that cut a deep groove in the brain. I trace the ongoing, victorious-feeling semi-starvation of my twenties directly back to adolescence - as a way of showing those assholes that I could control my appetites... Which is so sad, in retrospect, because of course no one cared.

The pressure to be thin, which causes guilt and obsessiveness around food, is terrible and starts so early. For me, it started at sixteen when I left home and gained weight for the first time and was told by a slightly older boy, out of the blue, that I was "too plump." The shock of that lasted a good long time.

I was also writing in a tradition and trying to do something different with it, something that hadn't necessarily been done before, which was a risk, but it made it interesting. My relationship with food has been complicated and rocky and not always wonderful, and it's a lens through which my entire life and identity are refracted.

Thank God for my hobgoblin, small-minded consistency.

Although the point of blogging is that it doesn't pay, I often steal from my blog for paid publication. I've based several magazine essays on blog posts, as well as an entire book.

I had to detach myself from myself, if that makes any sense, to conjure an authentic first-person voice. In that sense, it was similar to writing a first-person novel. But I was writing about real people, not fictional ones - myself, my family, my friends and boyfriends and ex-husband, and that was extremely tricky.
