Motivation is the key to all learning. Lack of motivation is perhaps the biggest obstacle faced by teachers, counselors, school/college/university administrators, and parents. Behavioral problems in the classroom often, or always, seem to be linked to the lack of motivation. Intelligent students are often out- performed by the less bright students with high motivation. If a student is motivated enough, s/he can accomplish learning of any scale. This paper, based on personal observation, focuses on some aspects of motivation as well as how teachers of English, can apply it to students. Our aim is to discuss how motivation in the classroom can help students develop their potentials and make them learn English effectively.
