John is the most diligent student in our class. He is one of my friends. As a matter of fact, he gets along with his classmates. He might spend just five to ten minutes talking to you once in a long while, but he talks with enthusiasm and energy, and he likes to share his thinking and ideas with you. He is honest; he does not like to waste his time and energy. He never appears sleepy and tired in the classroom. He always hands in homework on time and also does well in his examinations, yet he has time practicing playing football and his violin skill. I admire him. I hope I can be as diligent as he is; John is persistent, attentive, and energetic.
