When you create your effective learning environment,
The effectiveness comes from what you have no control over.
When you talk about the usefulness of your subject,
Its real use comes from something that has nothing to do with you.
The sticking point of all knowledge
Is to be found around the edges of the knowledge that has already stuck.
Focus on what you are bringing to the classroom and you will feel worthwhile;
Focus on what you are not bringing to the classroom and you will be worthwhile.
