Sun tzu said that

Used when someone says something so inspirational and wise that it sounded like it came straight out of "the art of war" by Sun Tzu

If fighting is sure to result in victory, then you must fight!' Sun Tzu said that, and I'd say he knows a little more about fighting than you do, pal, because he invented it, and then he perfected it so that no living man could best him in the ring of honor
