Here is a thought and I will explain how it pertains to the martial arts, at a philosophical level. Lets say you've got the distance of a mile to cover. You can walk the mile or you can run it. Running the mile is harder work than walking it but you get to your destination quicker so you save time. Walking is easier than running so by walking the mile you don't have to work as hard, but you don't finish it as soon, so what would you do?
