I used to be impolite. I only cared about myself. Over the years I have changed a lot. Now I have become more polite. When I meet teachers and parents, I always say “ hello ” to them. I am also willing to help others. I have become a volunteer and often give a helping hand to people in need. Moreover, I know it's important to protect the environment. I have developed a green lifestyle. I always turn off the tap while brushing my teeth. In this way, I can help save water and energy.
I will work harder to improve myself and make the world better.
