1. Proverb Praise of oneself is inherently worthless or dubious, as one cannot be objective of one's own work or accomplishments. So many companies claim to be the best in the business at this or that in their marketing, but self-praise is no praise, so I can never take them seriously. A: "I've got to say, I really did an excellent job on that project!" B: "Self-praise is no praise at all, Jim. Let's wait to hear what the boss thinks."

2. Proverb Praising oneself reveals one's arrogance or selfishness, which in turn lowers other's opinion of one. He's constantly bragging about how much money he makes and how important his job is, but he doesn't have any friends because no one can stand to be around him! Self-praise is no praise, after all. A: "Would you agree that you're one of the best musicians in the world right now?" B: "Self-praise is no praise at all, so I don't think it would be very seemly to try to answer that."
