Some say, life is a responsibility; responsibility to God, responsibility to parents, responsibility to society and what not! Some say, life is fun, a pure joy, an experience to be enjoyed as you live through. I think both the schools of thought are right. It is not one or the other; rather one and the other. That is, a responsibility and fun at the same time.
Life of a man is an experience of consciousness; it is a self conscious existence. That is, a man is aware of his actions. That is, he is aware why he does what he does and why he does the way he does. With this consciousness comes the responsibility. Responsibility to the self to make the most of his existence, and enjoy. And, a man is not an end in himself but rather a social being. He craves for a sense of belonging, and for support of fellow men; human achievements are never single handed though it might appear so many times.
