When I grow up, I want to be a teacher. Being a teacher has always been my ambition. I want to be a teacher because I love the idea of imparting my knowledge to the next generation. I believe that it is important for the country to have great teachers because we are moulding the next generation of leaders for the country. To be a successful teacher, I must make sure that I excel in my academic subjects, and at the same time, widen my horizon through readings.I must also ensure that I have high moral values as I will be looked up to as a role model by my students.
