We need to be ambivalent - in the essay, and in life too. Ambivalence - having mixed feelings, entertaining contradiction, living with fluctuation - is a widened embrace. It's about the coexistence of things, and in that light, we have no choice in the matter.

I have lots of fiction in the drawer, but the essays I mostly kick out into the world, ready or not. Fiction incubates differently, I suppose.

I suppose I like certainty as much as anyone else, but I also feel that the hidden costs are high, that we pay a heavy price for our convictions. This is a human issue as well as a writing issue - at least in the personal essay as I practice it. Any real essayist knows that certainty is an editorial decision, arrived at not through conviction but through suppression, the denial of a whole range of possibilities, of alternatives that we jettison, sometimes necessarily, in order to steady the ship.

I like the desperado aspect of essays, the free lance, that mercenary kind of thing, so I just do it, without asking anyone's permission. I've never written a query letter, I don't pitch pieces, I have no market in mind, I don't spend any time trying to figure out where I might fit in.

Even with an assignment, I take over, I find a freedom and make the idea my own, and that's where you get the sense that the essays become something very different than the original subject. Assignments are great, though - they test your mettle, your spirit and resilience. All of sudden you drop in, you don't know anything, you're vulnerable and available.

Really, I think among the many mistakes I've made over my life, one of them was caring so much about the short story.

What the nostalgic past and the imaginary future seem to share in common is a form of idealism, perhaps a dream of wholeness. Our future is just as goopy with sentiment as our past. To me, they're the same, both very tempting, and I don't believe in either, although the idealism is probably important.
