Generally when men are in a hurry, they do not do completely what they have to do or they do badly what they do. Well, there is a third way, it is to intensify one’s concentration. If you do that you can gain half the time, even from a very short time. Take a very ordinary example: to have your bath and to dress; the time needed varies with people, doesn’t it? But let us say, half an hour is required for doing everything without losing time and without hurrying. Then, if you are in a hurry, one of two things happens: you don’t wash so well or you dress badly! But there is another way—to concentrate one’s attention and one’s energy, think only of what one is doing and not of anything else, not to make a movement too much, to make the exact movement in the most exact way, and (it is an experience lived, I can speak of it with certitude) you can do in fifteen minutes what you were formerly doing in half an hour, and do it as well, at times even better, without forgetting anything, without leaving out anything, simply by the intensity of the concentration. And this is the best answer to all those who say, “Oh, if one wants to do things well, one must have time.” This is not true. For all that you do—study, play, work—there is only one solution: to increase one’s power of concentration. And when you acquire this concentration, it is no longer tiring. Naturally, in the beginning, it creates a tension, but when you have grown used to it, the tension diminishes, and a moment comes when what fatigues you is to be not thus concentrated, to disperse yourself, allow yourself to be swallowed by all kinds of things, and not to concentrate on what you do. One can succeed in doing things even better and more quickly by the power of concentration.
