Happiness includes chiefly the idea of satisfaction after full honest effort. No one can possibly be satisfied and no one can be happy who feels that in some paramount affairs he failed to take up the challenge of life.
Happiness is a matter of choice. Besides, sadness is also a matter of choice. So, which of the above habits or lifestyles have you been or are you indulging in? Anyway, I'm urging you as ever choose happiness rather than sadness. Because, happiness is a good antidote to stress. It equally guarantees and brings longevity. But, the reverse is the case with sadness. Or rather sadness shortens one's life span. Thus, say NO to sadness and then say YES to happiness. For, happiness pays rather than sadness.
Happiness is a matter of one's most ordinary everyday mode of consciousness being busy and lively and unconcerned with self. To be damned is for one's ordinary everyday mode of consciousness to be unremitting agonizing preoccupation with self.
