Before I started school, people felt that I was not going to be successful. At the age of four I started speech lessons because basically I could not speak well enough for anyone to understand me. The story goes downhill from here.

The first grade was a struggle. I not only had difficulty speaking, but also felt nervous about the fact that I was expected to learn to read and I just couldn’t do it. The second grade was not much better. I still struggled with the inability to read. It was in the third grade that the school district built a new school close to my home. I remember going there with my parents and helping to get the school ready so that we could move to the new one. However, things were still not much better as far as my schooling was concerned and did not get better for the next two years.

It was in the fifth grade. Mrs. Wakefield was my teacher, and if ever there was a teacher that deserved a gold star, it was her. She did not make me feel defeated. On the contrary, she did her best to let me know that I could be whatever I wanted to be. And that is just what I did.

For the past 22 years, I have been a fifth grade teacher. Because of Mrs. Wakefield’s influence on my life, I am now encouraging students who have had difficulties in their lives to believe that they can overcome any difficulty and become someone. I have won numerous awards up to now, such as Teacher of the Year. I owe it all to one fifth grade teacher who believed in me and challenged me to be all that I could be.
