You have to work hard to earn money.

A rich man often told his son, “Earning money is not that easy, it takes a lot of hard work, patience and sacrifice.” But the son would laugh off his father’s words without taking them seriously. One day, his father sent him on a job. After working hard in the sun and sweating all day, he received a little money. Then he realized how much trouble is hidden behind every penny. When he returned home, he apologized to his father and said, “You were right.” From that day on, he learned to understand the value of money and tried to be a hardworking and responsible person.
