He said so many memorable things to me that I continue to pass on to my students.  A few examples: “The worst crime you can commit as an artist is to bore your listeners”; for another, “People who come to hear you are entitled to hear all the rights notes, don’t you think?”; also,”You can’t play Mozart beautifully unless you can play Tchaikovsky well … and vice versa.” That last one made no sense to me at all at the time; now I understand precisely what he meant by it.
