I was born very, very lazy and I don't always practice very long. but I must say, in my defense, that it is not so good, in a musical way, to overpractice. When you do, the music seems to come out of your pocket. If you play with a feeling of 'Oh, I know this,' you play without that little drop of fresh blood that is necessary – and the audience feels it.
