People hate those who make them feel their own inferiority.

A man's fortune is frequently decided by his first address. If pleasing, others at once conclude he has merit; but if ungraceful, they decide against him.

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.

One man affirms that he has rode post a hundred miles in six hours; probably it is a lie; but supposing it to be true, what then? Why, he is a very good post-boy; that is all.

Learn to shrink yourself to the size of the company you are in. Take their tone, whatever it may be, and excell in it if you can;but never pretend to give the tone. A free conversation will no more bear a dictator than a free government will.

Whatever you do, do it to the purpose; do it thoroughly, not superficially. Go to the bottom of things. Any thing half done, or half known, is in my mind, neither done nor known at all. Nay, worse, for it often misleads.
