" Just about everyone I've ever interviewed has told me that by doing something or other--recovering from cancer, climbing a mountain, playing the part of a serial killer in a movie--they have learned something about themselves. And I always nod and smile thoughtfully, when really I want to pin them down: What did you learn from the cancer, actually? That you don't like being sick? That you don't want to die? That wigs make your scalp itch? Come on, be specific. I suspect it's something they tell themselves in order to turn the experience into something that might appear valuable, rather than a complete and utter waste of time.
In the last few months, I have been to prison, lost every last molecule of self-respect, become estranged from my children, and thought very seriously about killing myself. I mean, that little lot has got to be the psychological equivalent of cancer, right? And it's certainly a bigger deal than acting in a bloody film. So how come I've learned absolutley bugger all? What was I supposed to learn? I've found out that prison and poverty aren't really me. But, you know, I could have had a wild stab in the dark about both of those things beforehand. Call me literal-minded, but I suspect people might learn more about themselves if they didn't get cancer. They'd have more time, and a lot more energy. "
