Is any novelist going to recognize the moment when he or she has nothing more to say? It is a brave thing to admit. And since as a professional writer you are full of anxiety anyway, you could easily misread the signs.
Julian BarnesDoes character develop over time? In novels, of course it does: otherwise there wouldn't be much of a story. But in life? I sometimes wonder. Our attitudes and opinions change, we develop new habits and eccentricities; but that's something different, more like decoration. Perhaps character resembles intelligence, except that character peaks a little later: between twenty and thirty, say. And after that, we're just stuck with what we've got. We're on our own. If so, that would explain a lot of lives, wouldn't it? And also - if this isn't too grand a word - our tragedy.
