Perfection is not attainable, but if we chase perfection we can catch excellence.
March on. Do not tarry. To go forward is to move toward perfection. March on, and fear not the thorns, or the sharp stones on life’s path.
Aim at perfection in everything, though in most things it is unattainable. However, they who aim at it, and persevere, will come much nearer to it than those whose laziness and despondency make them give it up as unattainable.
