Truman Capote famously claimed to have nearly absolute recall of dialogue and used his prodigious memory as an excuse never to take notes or use a tape recorder, but I suspect his memory claims were just a useful cover to invent dialogue whole cloth.

When you want to get good at something, how you spend your time practicing is far more important than the amount of time you spend.
