“I had warned my father that my viva might mean a second. It meant a third, and I was overcome with regret, not, I am ashamed to say, for the giddy nights, but for the sober ones. I had not done much work, but I had done some. Had I known I was only to get a third I would not have wasted my time.”

Crazy Loco Love: A Memoir (2008)

The Age for Love
Context: I scribbled four pages which would have been no disgrace to the Journal des Goncourts, that exquisite manual of the perfect reporter. It was all there, my journey, my arrival at the chateau, a sketch of the quaint eighteenth century building, with its fringe of trees and its well-kept walks, the master's room, the master himself and his conversation; the tea at the end and the smile of the old novelist in the midst of a circle of admirers, old and young. It lacked only a few closing lines. "I will add these in the morning," I thought, and went to bed with a feeling of duty performed, such is the nature of a writer. Under the form of an interview I had done, and I knew it, the best work of my life.
What happens while we sleep? Is there, unknown to us, a secret and irresistible ferment of ideas while our senses are closed to the impressions of the outside world? Certain it is that on awakening I am apt to find myself in a state of mind very different from that in which I went to sleep. I had not been awake ten minutes before the image of Pierre Fauchery came up before me, and at the same time the thought that I had taken a base advantage of the kindness of his reception of me became quite unbearable. I felt a passionate longing to see him again, to ask his pardon for my deception. I wished to tell him who I was, with what purpose I had gone to him and that I regretted it. But there was no need of a confession. It would be enough to destroy the pages I had written the night before. With this idea I arose. Before tearing them up, I reread them. And then — any writer will understand me — and then they seemed to me so brilliant that I did not tear them up. Fauchery is so intelligent, so generous, was the thought that crossed my mind. What is there in this interview, after all, to offend him? Nothing, absolutely nothing. Even if I should go to him again this very morning, tell him my story and that upon the success of my little inquiry my whole future as a journalist might depend? When he found that I had had five years of poverty and hard work without accomplishing anything, and that I had had to go onto a paper in order to earn the very bread I ate, he would pardon me, he would pity me and he would say, "Publish your interview." Yes, but what if he should forbid my publishing it? But no, he would not do that.

Address at Bennington College (30 October 1984) as published in "Reflections of a Writer: Long Work, Short Life" in The New York Times (20 March 1988)
Context: I have written almost all my life. My writing has drawn, out of a reluctant soul, a measure of astonishment at the nature of life. And the more I wrote well, the better I felt I had to write.
In writing I had to say what had happened to me, yet present it as though it had been magically revealed. I began to write seriously when I had taught myself the discipline necessary to achieve what I wanted. When I touched that time, my words announced themselves to me. I have given my life to writing without regret, except when I consider what in my work I might have done better. I wanted my writing to be as good as it must be, and on the whole I think it is. I would write a book, or a short story, at least three times — once to understand it, the second time to improve the prose, and a third to compel it to say what it still must say.
Somewhere I put it this way: first drafts are for learning what one's fiction wants him to say. Revision works with that knowledge to enlarge and enhance an idea, to re-form it. Revision is one of the exquisite pleasures of writing: The men and things of today are wont to lie fairer and truer in tomorrow's meadow, Henry Thoreau said.
I don't regret the years I put into my work. Perhaps I regret the fact that I was not two men, one who could live a full life apart from writing; and one who lived in art, exploring all he had to experience and know how to make his work right; yet not regretting that he had put his life into the art of perfecting the work.
