Sturgeon's Law

Everyone in the world knows Murphy's law, and it's referenced to the point that I find it a little obnoxious. Sturgeon's law, on the other hand, is a beautiful little underused gem of an adage. These days it usually is stated as "90% of everything is crud," but I prefer the original: "nothing is always absolutely so."

Since the original has fallen out of common usage I'm going to start referring to it as "the lost law of Sturgeon," and attempt to drag it from its grave.
