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.

I occasionally play works by contemporary composers and for two reasons. First to discourage the composer from writing any more and secondly to remind myself how much I appreciate Beethoven.
