From a letter:
You write that you have taken a few years off from teaching to come to an understanding of “what it is all about.”
Tell me: once you have determined an answer to your question, what will you do then? And in the meantime, just who and how many have benefited from all your searching?
You will be more successful in your search if you go back to teaching and search there—while, in the meantime, you change the lives of your students.

Look what Allan said. Look what Ann said. We must always teach, because that is how we learn. I learned so much from one of my students last week.
As she told her story, the whole class broke into murmurs so she could not be heard. I said, "We are not here to judge or comment or give advice. We are here to listen to what she experienced."
And so they all listened attentively. It was a terrible thing to hear. We all learned something. No, we did not learn what it's all about. In fact, we learned a great question. But asking questions is an important part of what it's all about.
