If you are at all interested in teaching, then you know that becoming a teacher means way more than standing in front of a class and preaching a bunch of pointers about some subject. Teaching is about sharing knowledge and exposing others to ideas and ways to discover the world.
You can become a teacher of pretty much any subject and topic. Maybe you want to become a Kindergarten teacher or a university lecturer. Maybe you want to go into sports and become a Pilates instructor. Or maybe you want to explore the social sciences and teach people how to be tolerant towards one another. There are no limits to teaching, just as there are no limits to learning.
