The beauty of behaviour consists in the manner more than the matter…

Insult not another for his want of a talent you possess: He may have others which you want.

Praise your friends, and let your friends praise you.

He who knows the world will not be too bashful. He who knows himself will not be impudent.

If you mean to make your side of the argument appear plausible, do not prejudice the people against what you think truth by your passionate manner of defending it.

Do not endeavour to shine in all companies. Leave room for your hearers to imagine something within you beyond all you have said. And remember, the more you are praised, the more you will be envied.

If you give a jest, take one. Let all your jokes be truly jokes. Jesting sometimes ends in sad earnest.
