Quality is not an act, it is a habit.
The most effective way to do it, is to do it.
Never complain and never explain.
Be gentle to all and stern with yourself.
Be thine own palace, or the world's thy jail.
Wherever you are - be all there.
The wise does at once what the fool does at last.
Leap, and the net will appear.
Know or listen to those who know.
Well done is better than well said.
I wrote somewhere during the Cold War that I sometimes wish the Iron Curtain were much taller than it is, so that you could see whether the development of science with no communication was parallel on the two sides. In this case it certainly wasn't.
