Colleague Tim Miller sent this to me. The author is Jason Dias.

There was a certain town famous for its marketplace that had been set up in a riverbed after the river had been dammed. The market specialized in the valuable gemstones that could be found in the levee by the few who knew where to look. It was a challenge to dig them out of the dam, but it provided a good living.

Saul, being inexperienced, wanted to gather all the stones at once and sell them in one huge batch. Paul, being older and wiser, said, “You don’t want to dig out all the stones at one time. You’ll flood the market.”
