That's true! I am a licensed teacher. Being a teacher means opening your mind to helpful information that you can use to teach your students and by that you have to know well about the topic, if you are teaching a skill make sure to master that skill before teaching it. But teaching doesn’t mean that you should be the “best” in the room. You also have to open your mind with your students’ opinions because most of the times It is the teacher who learns from their students. It is the students who motivate us to strive to be a better teacher. Thus, we learn most by teaching.
