Teaching and Learning
If you see the opportunity to teach, give the lesson, especially if you have willing learners.
If you see the opportunity to learn, take it, especially if you have willing teachers.
The opportunities are not common. At least not as common as we need them to be to really see the world change.
But each of us can change our corner of the world by teaching a little more, and learning a little more.
Taking the opportunity every time it arises.
