I don't really think of my essays as being about myself. I know it sounds insane, but I just don't think of them as a memoir. They're essays; they're not an autobiography.

I loved Victoria Glendinning's bio of Vita Sackville-West. I also loved Michael Holroyd's immense biography of Lytton Strachey.
