Achievement of your happiness is the only moral purpose of your life, and that happiness, not pain or mindless self-indulgence, is the proof of your moral integrity, since it is the proof and the result of your loyalty to the achievement of your values.
I think that giving mindless praise is ridiculous. But I understand why parents do it. They want their kids to feel good about themselves. But parents are never going to teach their children true, positive self esteem by praising everything they do.
