How to be a good teacher?

Well, Mary want everybody write about this topic but...I don´t know the answer to it!!! If I had to prefer what kind of teacher I want to be, I would tell you that I would like to be this kind of teacher that you remember forever. I think a teacher never can be perfect because he/she is a person and there aren´t rules to be the best teacher. You can follow all the advices of other teacher, method of teching, use the best resources and never become in good teacher.
So, if you believe that you have the answer to this question, tell me, because In my opinion you are a good teacher when you use all what you know and you get the interaction and the communication with your pupils.
