Is happiness enough for good life? Does a person remain content and satisfied if he is happy and doesn't have anything else? Seligman suggests a hypothetical example, what if you could be hooked to an experience a machine that would keep you constantly happy or develops positive emotions you desire, no matter what happened in your life? would you experience abundance happiness all the time? Would you like to remain hooked up like this all the time? We may like this sort of situation for a while, because experiencing only one kind of emotion and having the same cheerful reacting to the various events of life and challenges actually impoverish the experience of life. So most of us would reject the experience machine because we believe that there are more important things in life than only happiness and subjective pleasure.
Aristotle has given the fullest expression in the writing about Eudemonic happiness. According to him, happiness is a self-realization meaning the expression and fulfillment of inner potentials. From this perspective it can be said that good life is a result of living in accordance with our daimon (in other words our true self). That means happiness results from striving towards self-actualisation a process in which our talents, needs and deeply held values direct the way we conduct our lives. We are most happy when we follow and achieve our goals and develope our unique potentials.
