The law of the instrument / by Mike Hudack

Best thing I've read lately is the Wikipedia page for the Law of the instrument:

The English expression "a Birmingham screwdriver" meaning a hammer, references the habit of using the one tool for all purposes, and predates both Kaplan and Maslow by at least a century.[9]

In 1868, a London periodical, Once a Week, contained this observation: "Give a boy a hammer and chisel; show him how to use them; at once he begins to hack the doorposts, to take off the corners of shutter and window frames, until you teach him a better use for them, and how to keep his activity within bounds."

Read the whole thing. It's applicable to your every day.
