For the first twenty-two years or so of our lives, our main “job” is learning. The bulk of our time is spent in classrooms acquiring new knowledge. And then, once we graduate, we feel like the education phase of our lives is done and now it’s time to go out into the world. Have you ever thought about how odd that idea is? That only a quarter of our lives should be devoted to learning, and then we should simply rest on our laurels for the remaining three-quarters of it?
