Having grown up so familiar with creating a pleasing facade, I now end up compelled to reveal things inside and say, 'Okay, now you really see me. Do you still love me?' And then it's never enough; it always has to be total self-revelation.
Whether writing fiction or nonfiction, I've never had the sense I was 'making up' a character. It feels more like watching people reveal themselves, ever more deeply, more intimately.
I admire writers who succeed at what I consider the first demand of art: that the artist vivisect himself without pity, without hesitation, determined to reveal whatever he might find.
