You know you've done a good job as a teacher when your students pass their tests and will be receiving their black belts in two weeks. You know you've done a really wonderful job when they bring you two dozen roses and a heartfelt, wonderful "Thank You" card for being there support team for the last five years.
I really don't know how I managed to stumble into this position, but I love the fact that I can help people achieve their goals. It makes me so happy. I never want to lose the ability to help my students. It really is what keeps me going.
