SELF-PRAISE

Goethe, Johann Wolfgang von
Say nothing of yourself, either good, bad, or indifferent; nothing good, for that is vanity; nothing bad, for that is affectation; nothing indifferent, for that is silly.

It is equally a mistake to  hold  one's self too high, or to rate one's self too cheap.

Hervey, George William
Self-praise occasionally succeeds with ignorant and credulous persons; very seldom with those who have much knowledge of the world. He who can make a discerning mind think more highly of him for what he says of himself, must be a person of unusual ability and address.

Montaigne, Michel E de
A man's accusations of himself are always believed; his praises of self never.

Rochefoucauld, Francois, Duc de la
We acknowledge that we should not talk of our wives; but we seem not to know that we should talk still less of ourselves.

Shakespeare, William
There is not one wise man among twenty will praise himself.

Xenophon
A man's praises have very musical and charming accents in the mouth of another, but sound very flat and untunable in his own.
