Teachers are the greatest role models a young child can have. While a mother and father can provide basic information about the world for a child, it takes the power of a professional teacher to change lives in a significant way.
Many people have fond memories of their years in high school and college. In many cases, an individual can remember a certain teacher or professor who had a profound impact on his or her educational experience. In some cases, a single teacher can steer a child from a life of crime towards a life of fulfillment.
Everything that humans enjoy in modern life is a result of education. When one visits a doctor, it's important to remember that all doctors must spend at least 10 years in a school being educated about medicine. This applies for all career fields ranging from engineering to logistics management.
With teaching, there's no limits to one's potential.
