I guess I'm coming from the wrong side. I think happiness for its own sake is really meaningless. I'd much rather struggle and advance than be happy doing nothing until I die, but I guess I'm in the minority. Happiness, to me, is a choice to not let negative things make you unhappy. You can acknowledge negativities and not be consumed by them.
Fighting for happiness is like fighting for peace. You win by not fighting anymore.
I'm sorry if this opinion somehow reads like satire.
