Do not sleep under a roof. Carry no money or food. Go alone to places frightening to the common brand of men. Become a criminal of purpose. Be put in… - Miyamoto Musashi

What is essential is to suddenly make a move totally unexpected by the opponent, pick up on the advantage of fright, and seize the victory right then and there.

"Holding the Long Sword Grip the long sword with a rather floating feeling in your thumb and forefinger, with the middle finger neither tight nor slack, and with the last two fingers tight. It is bad to have play in your hands. When you take up a sword, you must feel intent on cutting the enemy. As you cut an enemy you must not change your grip, and your hands must not "cower". When you dash the enemy's sword aside, or ward it off, or force it down, you must slightly change the feeling in your thumb and forefinger. Above all, you must be intent on cutting the enemy in the way you grip the sword. The grip for combat and for sword-testing is the same. There is no such thing as a "man-cutting grip". Generally, I dislike fixedness in both long swords and hands. Fixedness means a dead hand. Pliability is a living hand. You must bear this in mind."

It is better to be a warrior in a garden, than a gardener in a war.
