There is no such thing as perfection, there are only standards. And after you have set a standard you learn that it was not high enough. You want to surpass it.

Music has a lot in com­mon with math­e­mat­ics. But in music, two and two need not make four: they add up to what­ever you wish.

There is no top. There are always further heights to reach.

If I don't practice one day, I know it; two days, the critics know it; three days, the public knows it.

No matter what side of the argument you are on, you always find people on your side that you wish were on the other.

Can you appreciate music without playing it? Yes, you can. You can appreciate baseball without playing it. Many people attend a football game merely for the crowd, the excitement, the color.

The discipline of practice every day is essential. When I skip a day, I notice a difference in my playing. After two days, the critics notice, and after three days, so does the audience.
