Billy Joel was giving a master’s class at Vanderbilt University a few months ago. When a student asked Mr. Joel if he could accompany him on the piano, Mr. Joel said, “Okay.” (He discusses the experience briefly in this interview.) As you listen to the performance, you cannot doubt that the young man spends an enormous amount of time practicing. And Billy Joel … Well, he’s Billy Joel. He knows what he’s doing. Anyhow, simply enjoy the performance or use it as incentive to stick to your own “I’m going to do this every day” schedule, whatever this is.
