Imagine that you’re living in a tent on an open plain.
One day you plant a tree. For the next 40 years, you water it. You protect it from harsh weather and animals. You never pick its fruit. You don’t climb it for fun. You don’t take a break and rest in its shade. You don’t even cut down some branches to build a house. You never go anywhere or do anything else because you’re focused solely on growing that tree bigger and bigger.
