I've always been unhappiest when I sit down and try to decide if I am happy. I find I am happiest when I am thinking about my situation or life in general the least.

When reading the post about the example giving of the guy who seems happy I thought to myself, "this guy sounds a lot like me, why wouldn't he be happy?" I was disappointed to discover that the only reason he wasn't happy was because he is basically choosing to be unhappy in what seems like a good situation.
