Objectivism holds that for each person his own life is his ultimate value. Morally, the greatest thing one can do is to live robustly and to keep living. Happiness, in the Objectivist view, is the emotional experience of living well. Happiness is not a state one achieves, but the experience one has in the process of living a flourishing, robust life. Happiness is a complex emotion, involving many rather different subsidiary emotions, such as contentment, confidence, satisfaction, excitement, joy, and good cheer. These emotions generally proceed from achieving one's values, as when one feels joy and satisfaction over completing an important project, or as when one feels content after a good dinner. Happiness also proceeds from one's self-esteem, one's general sense that one is competent and worthy to be successful in life.
