Principle of escalating madness

From Geohashing
Now, if there is one thing you learn from geohashing, then that obstacles are overcome iteratively. If you have crossed obstacles or distances of various difficulties summing up to X, then encountering any obstacle of a difficulty x<X will make you say: "I didn't do all that X just to get thwarted by this x here." I call it the Principle of Escalating Madness, since it easily allows every new obstacle to be way larger than the ones you have encountered so far, if only you have overcome enough small obstacles before. And you've never heard of anyone being nettled-to-death-in-his-shorts, have you?
