Never write down your speeches beforehand; if you do, you may perhaps be a good declaimer, but will never be a debater.
Lord ChesterfieldPeople will, in a great degree, and not without reason, form their opinion of you upon that which they have of your friends; and there is a Spanish proverb which says vry justly, 'Tell me whom you live with, and I will tell you who you are.'
Lord ChesterfieldNever yield to that temptation, which, to most young men, is very strong, of exposing other people's weaknesses and infirmities, for the sake either of diverting the company, or of showing your own superiority. You may get the laugh on your side by it for the present; but you will make enemies by it for ever; and even those who laugh with you then, will, upon reflection, fear, and consequently hate you.
Lord ChesterfieldAn ignorant man is insignificant and contemptible; nobody cares for his company, and he can just be said to live, and that is all.
Lord Chesterfield
