I like Horowitz's way of dealing with critics:
After a particularly successful performance, a female critic came up to him and said that she adored his playing. He turned to her and said "lady, you can say what you like - it doesn't make any difference!"
I think that as pianists we so often have to display the courage of our convictions because we are so often subjected to critisism. The difference is that when we play badly enough for that criticism to be deserved, then we can become arrogant. When I recieve criticism for a good performance, I simply gesture to the piano and say "by all means, show me how you would have done it!" That will usually silence an arrogant critic!
Rubenstein said that "the best musicians are the best personalities." You will find, I think that the best pianists are the most humble.
A friend of mine worked as an usher at the Royal Festival Hall for a while. Pletnev came to perform Rachmaninov 3, and kicked up a fuss about everything - the lighting, piano stool, even the piano was changed for him and he still moaned. My friend told me that despite having his own way, he kept the audience waiting 30mins late, before eventually playing - BADLY!!! Now that's arrogance, but I say what goes around, comes around: he got what he deserved!
