At my age also I have no clear idea of true happiness. But I learnt that happiness can't be associated with our senses. Though it appears as nectar initially but it becomes poison at the end. As sweet is very favourite for many but ultimately turns you diabetic. Even in the human relationships we are blind folded to our kith and kin in affection. But real happiness comes from compassion to all unselfishly. Wish your success in the dynamics.
