How come people want to teach?

Teaching is such a large and vast profession and the reasons of while people choose the profession is just as broad. Some people want to teach because they want to change the lives of others and make a difference in the world. Others just love working with children and believe that teaching is the best route for them. There are so many reasons that make up the decisions of choosing teaching as a profession that you just lose track. After researching the question, "how come people want to teach", I found that there are even more reasons than I came up with.

Her reasons are primarily based on affecting the lives of students each day. The author feels that she is going to change the world with her students not only through curriculum based learning but with real life situations. She feels that teaching is the only occupation for her because of the feelings she will get when a student learns the curriculum they have been struggling for or a student who will tell her that she is a role model to them. I can really connect with this specific article because I feel the same exact way this author does about why I chose to become a teacher.

I found it interesting because it gives the opinion a lot of people have about teaching as a job. For example, it is definitely not for everyone because some people can barely be within a classroom for ten minutes with out wanting to pull their hair out. One of the points that I have never heard nor thought of was the control of the classroom. The article says that the teacher decides each day what will take place, it is one of very few jobs that allows you to control your work day. I believe teachers do have a lot of this control by deciding how things will be run and what will go on, but they do not have very much leniency for what they want to teach. The curriculum they are given is very strict especially when it comes time for MCAS.
