On the whole, obviously, the reason we have desires is because we think things will make us happy; but the truth is, desires themselves make us unhappy, because those thing that we desire don’t make us happy and the desires push us in a direction to do things that lead us to realizing that they are meaningless, the only thing that will make you happy, is living an altruistic life; in other words, it’s not that we don’t have to live in the physical; we don’t have to eat, we don’t have to sleep, we don’t have to procreate, we don’t have to make money; but as long as the ultimate goal of all those things is altruistic, is to be of ASSISTANCE to others, then every moment of your life is meaningful and that and only that can make you happy!
