There is a parable about two woodcutters. Determined to prove their superiority, they decided to have a competition to see who could cut the most trees down in one day. One woodcutter chopped on relentlessly, spurred on by the intermittent silence of his competitor whom he assumed was exhausted. But when the day ended, he discovered to his horror that his competitor had felled twice as many trees! His competitor had triumphed, simply because every-so-often he had taken time to sharpen his axe.
