"My job is teaching Middle School students, which I think is so important. The time I have been given with students is the period of life when their characters are changing the most. I can make a great influence on the lives of young people. Of all the things I could do, helping young people understand what is valuable and how to become valuable is the most important to me. Thus, teaching gives me a great deal of joy, and I hope I too can offer not only joy but understanding in reading, writing, and history."
