The man fixing my air conditioner looked up from his toolbox and said something I didn’t expect: “I love what I do. Even when I was a boy, I liked to help. It began with my finding beehives in trees, collecting the honey, and giving it to family and neighbors. Then, when I grew up, my interest turned to machines. I could have been a doctor or a nurse, but I chose to help people by fixing their air conditioning and heating. If they need cool air, I want to bring it, and if they need warmth, I want them to make sure they have it.”
