Do this thought experiment:
Pretend that you have nothing to do with students "getting it."
Pretend that a student acquires skills on their terms and in their own time.
Pretend that they're graced with understanding because they showed up, not necessarily because you spoke.
Pretend that you had nothing to do with their evolution.
just pretend. Do it. If you hesitate, you have a weak imagination.
Now...
throw away all those testimonials wherein you're praised for having an agreeable quality or likable demeanor.
Take all of it down off your site, your blog, your preferred virtual home d'ego.
Pretend no one has offered you feedback about your depth of knowledge or your gentle approach. Remove all the quotes.
Now...
who are you?
Can you get up tomorrow, inspired, ready to do it again?
If you can, you have strength of Spirit.
