I learn from thinking about the future, what hasn't been done yet. That's kind of my constant obsession.
Nobody can be so amusingly arrogant as a young man who has just discovered an old idea and thinks it is his own.
I took group lessons at a rink near my home. We first had to learn how to stand up on the ice wearing skates. Eventually we learned to move forward, but soon found out that it was not that easy to stop! So that was our next important lesson.
