If I don't practice one day, I know it; two days, the critics know it; three days, the public knows it. - Jascha Heifetz

No matter what side of the argument you are on, you always find people on your side that you wish were on the other.

Criticism does not disturb me, for I am my own severest critic. Always in my playing I strive to surpass myself, and it is this constant struggle that makes music fascinating to me.

Can you appreciate music without playing it? Yes, you can. You can appreciate baseball without playing it. Many people attend a football game merely for the crowd, the excitement, the color.
