I think there is much "invalid happiness", which just wastes our efforts and resources and leads us to human self-extinction.
(1) Happiness must be the short time feeling of things being a-step-better for keeping one's DNA alive. Or, there is no human in the world.
(2) To have happiness is easy if you quit the harmful "invalid happiness" that does not exist in our instincts. Over 90% of today's happiness is invalid. Invalid happiness leads us to doomsday!
