Self-praise is a form of pride and ultimately rings hollow. Genuine honour is conferred by others — it cannot be seized by the one who wants it. A person who praises themselves has no objective standing to do so; a stranger's praise, given freely, carries real weight. This is the wisdom of humility over self-promotion.
Memory phrase: Let others praise you.
Talk about it: Why does it feel different when someone else praises you instead of yourself?
Prayer: God, keep me from praising myself too much.
