One personal, or intrinsic, reward that drives my ambition is that I know that I would be helping some of the most needy in the education environment. I also know that helping people learn to communicate better inevitably helps society as a whole. Teaching is a very honorable profession. I believe that teaching is a calling for many people. Some know from a very early age that they want to be teachers.
Teaching is definitely a social service.
People are shaped, motivated, and inspired because of teachers. We are also better prepared for life because someone wanted to teach.
