Philip Stanhope, 4th Earl of Chesterfield

If you would convince others, seem open to conviction yourself.

Knowledge may give weight, but accomplishments give luster, and many more people see than weigh.

A wise man will live as much within his wit as within his income.

Pleasure is a necessary reciprocal. No one feels, who does not at the same time give it. To be pleased, one must please. What pleases you in others, will in general please them in you.

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.

The less one has to do, the less time one finds to do it in.
