I love teaching. What can I do other than becoming a school teacher?

If you don't want to be a school teacher, then you may try being a college professor or lecturer by clearing UGC NET, or you may be a research scholar Ph.D, where you will be delivering lectures to college students as a part of your Ph.D. Apart from this, you may be a counselor, or a Human Resource

Then, you can become a Lecturer in a college, or can become a Representative of any Industry, where your job will be to represent your Industry in various campuses.

To choose teaching as a profession, but not becoming a school teacher, you have to do postgraduate course and then UGC NET. And then, apply for lecturer or professor post.
