For me, playwriting is and has always been like making a chair. Your concerns are balance, form, timing, lights, space, music. If you don't have these essentials, you might as well be writing a theoretical essay, not a play.
What I'm exploring right now is the subject of my own mortality. It's an area that I'm curious about, and I'm researching it to see if there's a photographic essay in it for me. If images don't start to come, I'll go to something else.
At the age of 12 I won the school prize for Best English Essay. The prize was a copy of Somerset Maugham's 'Introduction To Modern English And American Literature.' To this day I keep it on the shelf between my collection of Forester's works and the little urn that contains my mother's ashes.
When I was ten, I wrote an essay on what I would be when I grew up and said I would be a professional soccer player and a comedian in off season.
In high school, I won a prize for an essay on tuberculosis. When I got through writing the essay, I was sure I had the disease.
I remember when an editor at the National Geographic promised to run about a dozen of my landscape pictures from a story on the John Muir trail as an essay, but when the group of editors got together, someone said that my pictures looked like postcards.
An essay is a thing of the imagination. If there is information in an essay, it is by-the-by, and if there is an opinion, one need not trust it for the long run. A genuine essay rarely has an educational, polemical, or sociopolitical use; it is the movement of a free mind at play.
My feeling is, when you are writing an essay, you don't make anything up. This may be a very Protestant notion, and I'm aware of the fact that memory is fallible, that if I had access to films or some absolute documentary evidence of what happened, it might look different; we get confused and fuzzy.
Criticism is, for me, like essay writing, a wonderful way of relaxation; it doesn't require a heightened and mediated voice, like prose fiction, but rather a calm, rational, even conversational voice.
I was uncomfortable writing fiction. My love was the personal essay, rather than the novel.
