“The world is a country which nobody ever yet knew by description; one must travel through it one’s self to be acquainted with it.”

“There are several short intervals during the day, between studies and pleasures: instead of sitting idle and yawning, in those intervals, take up any book, though ever so trifling a one, even down to a jest-book; it is still better than doing nothing.”

“Pleasure is the rock which most young people split upon: they launch out with crowded sails in quest of it, but without a compass to direct their course, or reason sufficient to steer the vessel; for want of which, pain and shame, instead of pleasure, are the returns of their voyage.”

“Lay down a method also for your reading; let it be in a consistent and consecutive course, and not in that desultory and unmethodical manner, in which many people read scraps of different authors, upon different subjects.”

“The steady and undissipated attention to one object is a sure mark of a superior genius; as hurry, bustle, and agitation are the never-failing symptoms of a weak and frivolous mind.”

“There is time enough for everything, in the course of the day, if you do but one thing at once; but there is not time enough in they year, if you will do two things at a time.”

“Listen to everything that is said, and see everything that is done. Observe the looks and countenances of those who speak, which is often a surer way of discovering the truth than from what they say. But then keep all those observations to yourself, for your own private use, and rarely communicate them to others. Observe, without being thought an observer, for otherwise people will be upon their guard before you.”
