It's always too early to quit.
Never complain and never explain.
Know or listen to those who know.
The most effective way to do it, is to do it.
Quality is not an act, it is a habit.
The dog that trots about finds a bone.
If you think you can do it, you can.
If you've got a talent, protect it.
Only the educated are free.
Either you run the day or the day runs you.
Certain kinds of speed, flow, intensity, density of attacks, density of interaction... Music that concentrates on those qualities is, I think, easier achieved by free improvisation between people sharing a common attitude, a common language.
