How do I become a teacher

Since I am posting this after the class is done I have the benefit of having already done the teacher certification assignment so at least I know what to expect when it comes time to do that. I think that becoming a teacher involves more then simply getting your certification and passing all your courses. Sure that means you can teach, but I don't necessarily think that means you're a teacher. I think I learned more about this in SED 125 then I did in this course. Hearing the panel of teachers speak and asking them questions was eye opening, especially when they spoke about teachers who were there simply trying to catch kids doing things wrong and should have gone into law enforcement instead. I guess my question would be how do I know when I've become a good teacher?
