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

In friendship, as well as in love, the mind is often the dupe of the heart.

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. Examine yourself, why you like such and such people and dislike such and such others; and you will find that those different sentiments proceed from very slight causes.

Assurance and intrepidity, under the white banner of seeming modesty, clear the way for merit, that would otherwise be discouraged by difficulties...

Pray be always in motion. Early in the morning go and see things; and the rest of the day go and see people. If you stay but a week at a place, and that an insignificant one, see, however, all that is to be seen there; know as many people, and get into as many houses as ever you can.

Mind not only what people say, but how they say it; and if you have any sagacity, you may discover more truth by your eyes than by your ears. People can say what they will, but they cannot look just as they will; and their looks frequently (reveal) what their words are calculated to conceal.

Wise people may say what they will, but one passion is never cured by another.
