There's a responsibility in being a person.
"There's a responsibility in being a person. It's more than just taking up space where air would be."- John Steinbeck.
As a human being we have certain obligations. We should be responsible and have duty to act in a certain way. For example we should take care of ourselves considering about others and should do something that contributes to our society.
Simply living life and occupying space in not what human life is about. We should live life that is active with purpose. We should live life so that we can make differences in the world. We should live our like to create positive impact in this world for we live our life only once.
