“ One can only develop an instinctive sense of distance if he is able to move about smoothly and speedily.
The quality of a man’s technique depends on his footwork, for one cannot use his hands or kicks efficiently until his feet have put him in the desired position. If a man is slow on his feet, he will be slow with his punches and kicks. ”
 Bruce Lee, Tao of Jeet Kune Do (1975). copy citation
