IT'S OKAY TO BE HAPPY
Happy people are more altruistic, they help out more, they have stronger relationships.
When we're unhappy, we tend to turn inward, dwell on our own problems and misery.
If it IS selfish to want to be happier, we should strive to be happy, if only for selfless reasons.
Happy people get more done while they're getting more out of life. IT'S OKAY TO BE HAPPY. It's morally "alright," in a world full of suffering, to seek to be happy.
