Once a man worries, he clings to anything out of desperation; and once he clings he is bound to get exhausted or to exhaust whomever or whatever he is clinging to. A warrior-hunter, on the other hand, knows he will lure game into his traps over and over again, so he doesn't worry.
The most effective way to live is as a warrior. A warrior may worry and think before making any decision, but once he makes it, he goes his way, free from worries or thoughts; there will be a million other decisions still awaiting him. That's the warrior's way.
