Suppose one finishes a first stab at some MATLAB code around 1 AM and decides to celebrate by having some sake and reading a little. One might then read a very anti-labor short story by Heinlein (“The Roads Must Roll”) and get a little irritated, and then decide to play some solitaire. And one’s solitaire game may end up with all cards face up except for three in the hand — the 4, 5, and 6 of diamonds, only in the wrong order. This might just tempt one to break the rules, just this once, to make oneself feel better. But then one would have cheated, and one couldn’t have that. Thus one is relegated to the legions of those who didn’t quite made it. Luckily, however, success at solitaire is not a universal measure of success, so one can sleep with full assurance that a lack of success at solitaire means very little in the grand scheme of things.
