But in the weeks after I learned that the breast cancer I have been in treatment for over the past year had spread to my bones — breaking my spine and becoming incurable and most likely fatal — finding the perfect living-room couch has begun to feel like the most important thing I’ve ever done.

I see the future as something that could come crashing down very fast. Let me put it slightly by way of a comparison. Normal people, and I use the term very deliberately, by this not otherwise able situation - I'm disabled. I'm abnormal. Normal people dont think very much about the medium term future. They think only about the present, which is constantly changing for them or the very far future, which is just an abstraction. For me, its the other way around, my present never changes. So I dont really think about. But the medium term involves my death so I'm quite conscious of what is going to happen to me in about a year, maybe two years, who knows, whereas no one else I know thinks like that.

I just thought right away that I wanted to work. ... This is a good job. It's been a good job. Work is the most effective drug there can possibly be. ... I'm on the periphery of a lot of despair, of course. ... You'd have to be stupid not to be. I have my moments when I'm not too thrilled about this whole deal. But at the same time, the songs have never come like this, so I'd have to feel more gratitude than anything else. I'm probably in the intensest creative period of my life.

I live by the day. Just sitting in the park, looking at the flowers thinking how beautiful they are. It's almost … not hallucinogenic but it's a much stronger feeling than previously. For me, at the moment, going for a walk in the park with Gail is heaven.

Yet one thing cannot be robbed of her futurity: my daughter, Cady. I hope I’ll live long enough that she has some memory of me. Words have a longevity I do not. I had thought I could leave her a series of letters — but what would they really say? ... There is perhaps only one thing to say to this infant, who is all future, overlapping briefly with me, whose life, barring the improbable, is all but past. That message is simple: When you come to one of the many moments in life when you must give an account of yourself, provide a ledger of what you have been, and done, and meant to the world, do not, I pray, discount that you filled a dying man’s days with a sated joy, a joy unknown to me in all my prior years, a joy that does not hunger for more and more, but rests, satisfied.

I remember the moment when my overwhelming uneasiness yielded. Seven words from Samuel Beckett, a writer I’ve not even read that well, learned long ago as an undergraduate, began to repeat in my head, and the seemingly impassable sea of uncertainty parted: “I can’t go on. I’ll go on.” I took a step forward, repeating the phrase over and over: “I can’t go on. I’ll go on.” And then, at some point, I was through.

I rolled back the images. Looked again. There it was. A new tumor, large, filling my right middle lobe. It looked, oddly, like a full moon having almost cleared the horizon. Going back to the old images, I could make out the faintest trace of it, a ghostly harbinger now brought fully into the world. I was neither angry nor scared. It simply was. It was a fact about the world, like the distance from the sun to the Earth.

Everyone succumbs to finitude. I suspect I am not the only one who reaches this pluperfect state. Most ambitions are either achieved or abandoned; either way, they belong to the past. The future, instead of the ladder toward the goals of life, flattens out into a perpetual present. Money, status, all the vanities the preacher of Ecclesiastes described, hold so little interest: a chasing after wind, indeed.
