If you think you can do it, you can.
To know oneself, one should assert oneself.
Be gentle to all and stern with yourself.
Wherever you are - be all there.
By failing to prepare, you are preparing to fail.
Quality is not an act, it is a habit.
If you've got a talent, protect it.
The wise does at once what the fool does at last.
Without hard work, nothing grows but weeds.
You never know what motivates 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.
