Write a letter to your friend who is a book-worm
My dear (Name),
You will not be a successful man if you remain a book-worm, you must know the world around you. I hope you know fully well the saying: "All work and no play, makes Jack a dull boy".
You should not shut yourself in a room reading all the time. It might tell upon your health and make you unfit for the practical life. True education means proper development of body, brain and mind. If any one of these faculties is neglected, you will surely come to grief.
You must participate in games and take light exercise daily. It will refresh your mind and body. Recreation of the mind is necessary. There should be proper coordination between studies and games.
I hope you will pay attention to what I have said above.
