The teacher is the kingpin of the educational situation. He makes or breaks programs. I touch the future. There is no wrong time for learning. It may be the wrong time for what the teacher had planned to teach, but just as certainly it will be the perfect time to teach something else.
Teachers learn to grasp the moment.
Any time a student is there before you, the possibility is present, the moment is yours. I suspect they know in their hearts they've done a good thing, too, and are more satisfied with themselves than most people are. Most of us end up with no more than five or six people who remember us. Teachers have thousands of people who remember them for the rest of their lives. The curriculum is so much necessary raw material, but warmth is the vital element for the growing plant and the soul of the child.
