Which stage of a man’s life depicts him as an egoistic person? What’s the reason behind his ego? Discuss the values a man should possess to become selfless in life.

According to Shakespeare, a soldier is as ferocious as a leopard. He is aggressive and short-tempered. He picks up quarrels for the smallest reasons and is willing to die for the sake of his honour. This stage of life depicts him as an egoistic person. The reason behind his ego is his feeling of wanting to protect his reputation at all costs, even his life. To become selfless, the values a man must possess are totally the reverse — he should be even-tempered, calm and of an endearing nature.
Like a soldier, I too want to be courageous. The soldier’s willingness to put his life at stake for his country’s honour impresses me the most.
