“I have written the history of my life, and I have a perfect right to do so; but am I wise in throwing it before a public of which I know nothing but evil? No, I am aware it is sheer folly, but I want to be busy, I want to laugh, and why should I deny myself this gratification?”

Response to a would be biographer in 1980, as quoted in "When Stephen met Sylvia" in The Guardian (24 April 2004) http://books.guardian.co.uk/review/story/0,12084,1201328,00.html
Context: I am very honoured by your wanting to write a life of me. But the fact is I regard my life as rather a failure in the only thing in which I wanted it to succeed. I have not written the books I ought to have written and I have written a lot of books I should not have written. My life as lived by me has been interesting to me but to write truthfully about it would probably cause much pain to people close to me — and I always feel that the feelings of the living are more important than the monuments of the dead.
