The wise does at once what the fool does at last.
Know or listen to those who know.
If you're going through hell, keep going.
To know oneself, one should assert oneself.
Begin to be now what you will be hereafter.
It's always too early to quit.
If you think you can do it, you can.
Never complain and never explain.
Quality is not an act, it is a habit.
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.
