If you think you can do it, you can.
It's always too early to quit.
I can, therefore I am.
The most effective way to do it, is to do it.
Problems are not stop signs, they are guidelines.
Quality is not an act, it is a habit.
Either you run the day or the day runs you.
The dog that trots about finds a bone.
The wise does at once what the fool does at last.
Expect problems and eat them for breakfast.
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.
