Danh ngôn của Philip Stanhope, 4th Earl of Chesterfield (Sứ mệnh: 7)

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.
Good humor is the health of the soul, sadness is its poison.
Regularity in the hours of rising and retiring, perseverance in exercise, adaptation of dress to the variations of climate, simple and nutritious aliment, and temperance in all things are necessary branches of the regimen of health.
Know the true value of time; snatch, seize, and enjoy every moment of it. No idleness, no laziness, no procrastination: never put off till tomorrow what you can do today.
In seeking wisdom thou art wise; in imagining that thou hast attained it - thou art a fool.
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.

To have frequent recourse to narrative betrays great want of imagination.
Knowledge may give weight, but accomplishments give luster, and many more people see than weigh.
Knowledge of the world in only to be acquired in the world, and not in a closet.

Women are only children of a larger growth. A man of sense only trifles with them, plays with them, humours and flatters them, as he does with a sprightly and forward child; but he neither consults them about, nor trusts them with, serious matters.
Whoever incites anger has a strong insurance against indifference.
Never seem more learned than the people you are with. Wear your learning like a pocket watch and keep it hidden. Do not pull it out to count the hours, but give the time when you are asked.
