Great merit, or great failings, will make you respected or despised; but trifles, little attentions, mere nothings, either done or neglected, will make you either liked or disliked in the general run of the world.

The only sure way of avoiding these evils [vanity and boasting] is never to speak of yourself at all. But when, historically, youare obliged to mention yourself, take care not to drop one single word that can directly or indirectly be construed as fishing for applause.

Pocket all your knowledge with your watch, and never pull it out in company unless desired.

The vulgar only laugh, but never smile; whereas well-bred people often smile, but seldom laugh.

Speak the language of the company you are in; speak it purely, and unlarded with any other.

Whatever is worth doing at all is worth doing well.

Those who see and observe kings, heroes, and statesmen, discover that they have headaches, indigestion, humors and passions, just like other people; every one of which in their turns determine their wills in defiance of their reason.
