“If you want to live a happy life, tie it to a goal, not to people or things.”
Albert Einstein
It is well-said by Albert Einstein. To have a good life, it is essential to set a goal and start working on it from the beginning. Whatever we aim for, our lives should be designed around it. Some people aim to become doctor and some want to be engineer. Every goal is achievable if we work hard.
I want to be a teacher when I grow up. My goal is clear and my vision is vivid. I want to educate people. Science is my favorite subject. It always opens my mind to new dimensions. I want to be a science teacher who practically teaches students, along with theory. 
Teachers help not only few people but they have power to educate whole generation. I want to transfer my ideas to one generation. I know one man has power, but we can change whole nation if others also join in. I want to teach good ethics along with my subject to improve our lives and others. I am sure that I will achieve my goal because I am determined.
