You might not always feel confident that you are a good teacher. That’s okay though, as long as you know how to be a good student.
Taking the seat of the student gives you permission not to know. In the not knowing lies the vast expanse of possibility and discovery. In this space you have the freedom to explore, experiment, ask questions, break out the books, clarify, try things out, make mistakes and learn from them.
When in doubt, become a better student.
