I've learned to organize a class without refering to my sequence notes, everything is in my mind.
I've learned to not use the "I want you to..." instructions too much. Thanks to Jaclyn, simpler and straight-to-the-point instructions are easier to be catched. And my instructions now don't sound so demanding (like a kid).
I've learned how to observe and take care of the elderly in class.
I've learned that, it's not possible to please everyone. I'm utterly greatful to those who allow me to spread the goodness into them.
