In this way the responsibility of building my future is in my hands, but the future is uncertain and so I have no escape from anxiety and despair. Sartre is of opinion that many paths are open before us and among them we choose one. But as we are not able to choose the other opportunities, we are always under the shadow of anxiety. Higher the man's responsibility leads to higher anxiety. It is deeply related to our existence.
Man is characterized by freedom.
This free individual is also a creative individual i.e. we create our own personality, situation by interpreting our environment and in this way we are also responsible. Man is always responsible for his choice. He blames himself and not the society for the consequence of his choice . Man through his free acts determines his own destination. Man in making his personality, is never complete through out his life, he develops by his own free choice.
