self-praise is no recommendation (at all)

1. Proverb Praise of oneself is worth nothing, as one cannot be objective of one's own work or accomplishments.

A: "This is the best work we've ever done. People are going to absolutely go crazy for it!" B: "Self-praise is no recommendation at all, Jim. We'll have to wait and see how it does on the market."
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 recommendation, after all. A: "Would you agree that you're one of the best musicians in the world right now?" B: "Self-praise is no recommendation at all, so I don't think it would be very seemly of me to answer that."
