a little boy standing next to a tree

A boy visits his grandfather during the summer and asks how to become successful. Instead of directly answering, the grandfather planted two plants—one is planted inside the house, and the other outside. After four years, the boy returns, and they check on the plants. The one inside is small, while the one outside has grown into a large, strong tree.The grandfather explains that the plant outside faced many challenges, like storms and harsh weather, which made it stronger, while the plant inside, shielded from difficulties, remained weak. He teaches the boy that, like the plant, facing challenges in life makes us stronger and more successful.
