When the hour of dire need draws nigh Keep the faculty of effort alive in you by a little gratuitous exercise every day. That is, be systematically ascetic or heroic in little unnecessary points, do every day or two something for no other reason than that you would rather not do it, so that when the hour of dire need draws nigh, it may find you not unnerved. William James, Principles of Psychology wisdomneed
Useless work on useful things Anyone can verify by simple observation two important facts. The first is, that whenever humans design and make a useful thing they invariably expend a good deal of unnecessary and easily avoidable work on it which contributes nothing to its usefulness. The second fact is that all useful devices have got to do useless things which no one wants them to do. Who wants car to get hot? Or to wear out its tires? Or to make a noise and a smell?
