He often visited his field to check on the growth of the crops, making sure they received enough water and sunlight. He never idled or complained about the hard work, because he knew that only by paying the price of sweat could he reap the rewards of harvest. One day, the farmer noticed that his corn seedlings were not growing well. He worriedly observed them, trying to find the reason.
