Shakespeare has beautifully compared the growth of humans by stages with his emergent role during that stage. In the first stage man plays the role of an infant. As an infant, he does represent characterisation of mewling and puking. In the second Act, he does the role of a school boy with the characteristics of unwillingness to go to schools and innocence shining in his face. In the third Act, he performs the role of a lover head over heels in love with a beautiful lady. He composes woeful romantic ballads and sings serenades to impress his love. In the fourth act, he plays the impressive role of a shorttempered, honour pursuing soldier. 

He is ready to put his mouth in the Cannon’s mouth for conquering the bubble like honour in order to defend the territory of his countiy. In the fifth Act, he performs the role of a mature and fair judge criticising the ways of the world often spicing up his conversations with wise remarks and wit. His pot belly and well-cut beard shows the social status he enjoys in life. In the sixth act, he is old. He performs the role of a thin old man wearing ill-fitting loose garments with a changed treble in his voice.

He is bespectacled and slow in walking. In the final act, he becomes a total invalid losing all senses of hearing, taste and sight. Then the performer leaves the stage (i.e.) the lonely planet.

How according to the poet is it possible for his son to bring changes into a world that resents change? The poet advises his son to introspect often and not feel ashamed of being called a fool especially when he pursues knowledge. He can examine himself and remove his follies. He must enjoy the advantages of solitude. Solitude would help him to be creative. He would invariably learn that final decisions are always taken in silent rooms. Being alone, he can identify his innate potential and talents. His free imagination will bring about changes even if the world resents them. The zest to bring about changes will elevate him to the level of Shakespeare, Pasteur, Wright Brothers, Pavlov and Michael Faraday. Thus he will be remembered as one of the great men who changed the world.
