"There are situations in life which are beyond one. The sensi..." — P. G. Wodehouse quote meaning

There are situations in life which are beyond one. The sensible man realizes this, and slides out of such situations, admitting himself beaten. Others try to grapple with them, but it never does any good. When affairs get in a real tangle, it is best to sit still and let them straighten themselves out. Or, if one does not do that, simply to think no more about them. This is Philosophy. The true philosopher is the man who says "All right," and goes to sleep in his arm-chair. One's attitude towards Life's Little Difficulties should be that of the gentleman in the fable, who sat down on an acorn one day and happened to doze. The warmth of his body caused the acorn to germinate, and it grew so rapidly that, when he awoke, he found himself sitting in the fork of an oak sixty feet from the ground. He thought he would go home, but, finding this impossible, he altered his plans. "Well, well," he said, "if I cannot compel circumstances to my will, I can at least adapt my will to circumstances. I decide to remain here." Which he did, and had a not unpleasant time. The oak lacked some of the comforts of home, but the air was splendid and the view excellent.
