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
Wear your learning like your watch, in a private pocket; and do not pull it out, and strike it, merely to show that you have one. – Lord Chesterfield
