Mnemonic

A retainer trusted with the lord's money counts every coin once more before reporting. This careful double-checking is what makes him truly intelligent. Any fool can count once, but a wise retainer always verifies the money once more.
Additional thoughts
Picture a loyal retainer at a candlelit desk, meticulously recounting stacks of coins. His habit of always verifying once more is precisely what earned him the reputation as the most intelligent advisor in the entire court.
Quick recall
The retainer recounts the money once more — that's what makes him intelligent.
