Once upon a time, there was a 12-year-old boy who lived in a village with his parents. One day, after many years, he visited his grandfather's village. There, he spent all his time playing with his grandfather. While playing one day, the boy told his grandfather, "Grandpa, when I grow up, I want to become very successful. Can you give me some tips on how to achieve success?" His grandfather smiled, looked at him, and agreed.
