Before I get started I’d like to share William Shakespeare point of view that he has presented in "All the world's a stage", that when a child born he’s unable to do anything he just weeping in the arms of the nurse after that he become a little bit bigger and start to run here and there and also go to school unwillingly along with his bag on his shoulders. After this he become teenager and start to do love and after that time period he become a strong and brave young man to have beard on his face like a leopard and join army.
