Whatever is worth doing at all is worth doing well. – Lord Chesterfield
The world can doubtless never be well known by theory: practice is absolutely necessary; but surely it is of great use to a young man, before he sets out for that country, full of mazes, windings, and turnings, to have at least a general map of it, made by some experienced traveler. – Lord Chesterfield
Never seem wiser, nor more learned, than the people you are with. Wear your learning, like your watch, in a private pocket: and do not merely pull it out and strike it merely to show that you have one. – Lord Chesterfield
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. – Lord Chesterfield
