I think we are all teachers and learners at the same time. It doesnt take a classroom and students to say you are a teacher. When you give advice to someone or help them with something, you impart knowledge or a skill to that person..and you also learn in the same way from others

Everyone is teacher in their own life and ways .. i believe only teaching Maths, Science is not teachers job ... but to day to day activities for younger ones is also teaching

Yes in sence we are all teachers but in my case That's what I study at university, it was not my first option but I just dind't want to stop studying after I finished highschool. The difference is that not all of us will have to teach to a numerous public everyday. I don't hate it but I find it really challenging because it is diffcicult to find the best tecnique and strategy to draw students attention and finally convey knowledge .
