Well, sometimes being happy is NOT a choice. Sometimes your whole World falls apart and your life goes into crap mode. Like a guy I knew who lost his house due to some legal trouble, his car got wasted in a car crash shortly after, his wife left him, and he was totally broke. Cant blame him for not being happy. Could only be happy by doing some hard drugs or something. There is a chance for him to be happy in the future but certainly not now.
