The main idea is to assess if the factors of being, thinking, doing and having are the true desired as it comes from within us or from our soul consiouness , or are imposed from outside centers of power. In addition of course this is based on that the desired is the correct inner desire and not a false external desire. Finally if Being , thinking , doing and having corresponds to the true inner desire, then this is measured as Happiness.

Finally we take the weighted average of H(have), H(Do), H(think_n_feel), and H(Be), with weights say 1,2,3,4, (=10) that is Total happiness=(H(have)+ 2*H(Do)+ 3*H(think_n_feel)+ 4*H(Be))/10.
Some people would argue that the weights should be in the reverse order, with the weight on the happiness of "have" equal to 4, but personally I prefer, the weight so that the happiness of "Be" is of the highest weight.
This would be are total happiness average index, for the last 5 years!.
Of course peace of mind and happiness comes also when we feel that we accomplish gradually our true goals. And there are minor and major goals in life. We might say that our existence has no other goal than to exist. Or that we may have many different goals, according to the scale of relevance in our existence. But one of the most beautiful and meaningful goals in life is to develop more of our soul consciousness. So all other minor goals like social success, money, fame, knowledge , creativity etc are to serve this major goal of developing more of our soul consciousness
