Like Hock, Johannes Liechtenauer tried to teach people to survive violent encounters (he just did it over 600 years ago)! Although his writing was directed toward medieval swordsman, I think the basic principle below still holds true for knife, stick, and even gun. I guess it shows that the real "Truths of Combat" remain unchanged

...
"In 1389 fencing master Johannes Liechtenauer wrote of the need to keep up aggressive motion during a fight. Liechtenauer said, “If someone fights…he should be in the movement, and not in the rest.” He stressed the necessity of “being steadily moving” and declared that “constant movement comprises the beginning, the middle and the end of all swordsmanship.”…He urged combatants to deliver “one attack after the other, always in the movement, no matter whether you hit or miss.” Whenever cutting or thrusting, he recognized that “striking, thrusting, or cutting, with stepping out or in, passing around or leaping” were necessary to extend the sword’s point forward. You must “step backwards or forwards, as it occurs, firmly and skillfully, rapidly and quickly.” Liechtenauer’s instructions on the use of the long sword…advised specifically that one should not remain too long in fighting stances, because he “who is still is dead, he who moves still lives.” He added that one should “move to fight instead of waiting in the guard and waste the chance [to attack].”"
