A boy put his hand into a jar(罐子) full of nuts(坚果).
He grabbed(抓住) as many as he could, but when he tried to pull out his hand, he couldn’t, because the neck of the jar(罐子) wasn’t wide enough.
Not wanting to lose his nuts(坚果), and yet unable to take out his hand, he felt disappointed and started to cry.
Someone said to him, “Be satisfied with(满意) half the amount, and you will easily pull out your hand.”
MORAL: Do not attempt too much at once.
