"If I go without playing for ten days, I feel that something is missing. I lose a certain confidence. I know that I will subsequently need to take much more time to do the technical and physical work which will allow me to regain the same mastery of the instrument.

Two hours a day is already enough to preserve one's form. But working on the piano and music are two different things. I could not imagine ten days without music! "
