“At my age, one should be aware of one's limits, and this knowledge may make for happiness. When I was young, I thought of literature as a game of skillful and surprising variations; now that I have found my own voice, I feel that tinkering and tampering neither greatly improve nor greatly spoil my drafts. This, of course, is a sin against one of the main tendencies of letters in this century--the vanity of overwriting-- ... I suppose my best work is over. This gives me a certain quiet satisfaction and ease. And yet I do not feel I have written myself out. In a way, youthfulness seems closer to me today than when I was a young man. I no longer regard happiness as unattainable; once, long ago, I did. Now I know that it may occur at any moment but that it should never be sought after. As to failure or fame, they are quite irrelevant and I never bother about them. What I'm out for now is peace, the enjoyment of thinking and of friendship, and, though it may be too ambitious, a sense of loving and of being loved.”
