Teachers are talented professionals but, frankly, nobody cares. Very few private companies will pay their teachers well. They will demand CELTAS, DELTAS, and degrees but pay the same hourly rate as someone with an unskilled job.
The best thing about teaching, even after all these years, is the students. To help someone along the road to pass an exam or get a promotion is deeply satisfying. To do that well you need empathy. It is the one quality that all great teachers have; wherever they are from and whatever they teach. Understand what your students are feeling. What is good for one student will not work with another. Never ever let a methodology get in the way of good teaching. Be present in the here and now with your students.
Teachers are by their very nature generous people. Teaching is one of the many shades of love. If you know stuff, share it with less experienced colleagues. If you need help, ask. Teachers enjoy sharing resources, creating new things with other teachers, and giving their opinions.
