I never was very capable of expressing my feelings or emotions in words. I don't know whether this is the cause why I did it in music and also why I did it in painting. Or vice versa: That I had this way as an outlet. I could renounce expressing something in words.

I owe very, very much to Mozart; and if one studies, for instance, the way in which I write for string quartet, then one cannot deny that I have learned this directly from Mozart. And I am proud of it!
