Never talk of Yourself.

Never talk of Yourself. You must either praise yourself, which is vain, or blame yourself, which is little-minded:it ill beseems him that speaks, and ill pleases him that hears. And if you should avoid this in ordinary conversation, how much more in official matters, and above all, in public speaking, where every appearance of unwisdom really is unwise. The same want of tact lies in speaking of a man in his presence, owing to the danger of going to one of two extremes: flattery or censure.
