We should be careful to get out of an experience only the wisdom that is in it—and stop there; lest we be like the cat that sits down on a hot stove-lid. She will never sit down on a hot stove-lid again—and that is well; but also she will never sit down on a cold one anymore.
There are those who imagine that the unlucky accidents of life—life's "experiences"—are in some way useful to us. I wish I could find out how. I never know one of them to happen twice. They always change off and swap around and catch you on your inexperienced side. Taming the Bicycle (1917)
