When you do things right, people won’t be sure you’ve done anything at all.
Does anyone know of an earlier source than Futurama?
I think that, within limits, it is right. If it were right more generally, then Reggie Jackson was doing the wrong thing by whacking three straight pitches over the fence in 1977 Game Six. :) But, if you think to the Karate Kid movie, and how Pat Morita trained whatshisface, that’s more like it, not just in how he trained the hands and feet, but also attitude and personal grace—the kid wasn’t completely aware that this was happening.
(I point to a popular movie rather than real life, because I need a simple and familiar example.)
