The art of doing more while looking like you're doing nothing at all.
means The state of getting the most done with the least wasted effort, time, or resources.
from From Latin 'efficere,' to accomplish or bring about — built from 'ex-' (out) and 'facere' (to make or do), the same 'facere' lurking inside fact, factory, and affect. The word arrived in English through 'efficient,' first describing a cause that actually produces its effect, before it drifted into the modern sense of doing things well and sparingly.
