Who determines the height of success?

Who determines the height of success?  Is it the society ? or is it yourself? What I perceive or set as success for myself will not be success for another.  How can you then say a person is successful or not? Does success mean one should be rich or does it mean one should be happy in what he/she does?  If you have set a goal and you accomplished it, isn't that success. Success means going to bed at night knowing that you have given everything you have in order to built your empire. You cannot do everything at once, but give your all to what you do. You alone can only define how successful you are. You are the boss of your own empire, your own conscious. If  you think that you want something, you have all the power to go and get it. You are youelr own power house. This is something that has benn crossing my mind lately.
