A Dialogue about the proper use of time

Myself: Good morning, Sabbir.

Sabbir: Good morning. How are you?

Myself: I am fine. Why do you seem so down?

Sabbir: I've performed poorly in the examination. 

Myself: I believe it's because you haven't been managing your time effectively.

Sabbir: You're absolutely right. I often waste a lot of time watching TV and don't prepare my lessons on time. Can you give me some advice on what to do?

Myself: Certainly! Keep in mind that those who make the best use of their time can achieve great things in life.

Sabbir: Does that mean I can't watch TV at all?

Myself: No, you can watch TV, but make sure to do it only after you've prepared your lessons.

Sabbir: Thank you for your suggestions.

Myself: You're welcome.
