From an anecdote by Martin Amis:

Saul Bellow himself wrote that as he gets older everything he reads… strikes him as not short enough.

I was doing a class with him last year on Conrad’s The Shadow Line, one of Conrad’s novellas, and we were saying, “What was this novel about?” And someone said rhetorically, (I mean you can’t say what’s a novel about) “What’s Augie March about?” And Saul replied, “It’s about two hundred pages too long.”
