How is the brain and the military alike? Less is more. By that I mean for the brain, it isn't about working hard, its about working efficiently, since studies show the better a person is at a task, the less the brain works to perform it. And for the military, it isn't about bringing more firepower, it's about putting minimum firepower precisely on the target -- again, it's not about working hard, its about working efficiently.
And I don't think those are the only two areas where this applies.
