...you spend a lot of time reflecting on your own learning style.
...you take pride in being able to explain something in several different ways.
...you can empathize with someone trying to understand a concept they've never encountered before and you respect their struggle. You remember what it was like when you were in their shoes.
...you don't just talk to your students. You listen to them too.
...you're humble enough to admit when you don't actually know something. You refuse to give wrong or made-up information for the sake of your pride.
...you're wise enough to know the difference between when your student needs to be gently pushed into working on a difficult concept and when that concept needs to be placed on the back burner for a while.
...you understand that "those who can't do, teach" is a total myth, but instead of getting angry at people who claim that to be true, you work to demonstrate that teaching is a calling, and an honorable one at that.
