Play difficult and interesting things. If you play boring things, you risk losing your appetite. Saxophone can be tedious with too much of the same.

Be interesting, be enthusiastic... and don't talk too much.

The saxophone is a very interesting machine, but I'm more interested in music.

Know not to revere human things too much.

You get bored if you do the same thing too much.

When you work too much, you are boring - that is possible. But to have a happy life, if you can do several things in the correct way, that is perfect.
