You might think that after 40 years of practice you wouldn't need to practice anymore, but sadly it doesn't work that way. You still have to keep chugging away and perfecting.
I'm in a position where, theoretically, I could play the same ten concertos and make a very good living bouncing around playing Mendelssohn, Tchaikovsky and Barber, but I really think artists should keep pushing limits and trying new things.
I use Facebook quite a lot to keep up with my friends, although I had to delete 'Words With Friends' from my phone because it was wasting too much of my time.
Stradivarius, in particular, was the most amazing craftsman and one of the great artists and scientists that ever lived because he figured out something with the sound and the science of acoustics that we still don't understand it completely.
Good conductors know when to let an orchestra lead itself. Ninety percent of what a conductor does comes in the rehearsal - the vision, the structure, the architecture.
I want to do everything. That's my problem. Life is short, and I hate the idea of turning down anything. You never know what interesting experience might happen.
Criticism is always hard to take - we musicians are sensitive. It's always hard when someone says something negative - but you try to learn to just let it roll off and not worry about it.
For some reason I can't explain, artist and musicians tend to look younger than our age. Being in music, you need this youthful sense of discovery and wonder for what you're doing and keep your imagination open. That's a youthful way of looking at life and I think that reflects in how you age.
