From The Chuang Tzu
Free and Easy Wandering
Hui Tzu said to Chuang Tzu, "I have a big tree named ailanthus. Its trunk is too gnarled and bumpy to apply a measuring line to, its branches too bent and twisty to match up to a compass or square. You could stand it by the road and no carpenter would look at it twice. Your words, too, are big and useless, and so everyone alike spurns them!"
Chuang Tzu said, "Maybe you've never seen a wildcat or a weasel. It crouches down and hides, watching for something to come along. It leaps and races east and west, not hesitating to go high or low-until it falls into the trap and dies in the net. Then again there's the yak, big as a cloud covering the sky. It certainly knows how to be big, though it doesn't know how to catch rats. Now you have this big tree and you're distressed because it's useless. Why don't you plant it in Not-Even-Anything Village, or the field of Broad-and-Boundless, relax and do nothing by its side, or lie down for a free and easy sleep under it? Axes will never shorten its life, nothing can ever harm it. If there's no use for it, how can it come to grief or pain?"
I would just like to point out, for those of you in similar situations, that you can also use it to make wood chips for smoking things like ducks, sausages, and Gnarled Tree-grilled Flank Steak
