I won't deny that it's easier for people to be happy in some situations than in others, Mickey. ;-)

However, my point was that most people seem to decide not to be happy a great deal of the time. It becomes their normal mode of existence. That's their choice. I have spent great long swaths of my life in an overall unhappy condition...despite the fact that I had enough money, enough food, a place to live, and things were basically okay in most respects. To feel unhappy despite all that was my choice. And I know it. I bet I've been more unhappy than happy for, oh, at least half of the days of my life up till the present moment, maybe more than half. Very little of that had to do with the actual outer circumstances, it almost all had to do with my inner perception of the outer circumstances, my expectations, and my reaction to my inner perception. I have a PHD in how to be unhappy.

Since I'm so good at it, I also tend to notice when other people do it. ;-) I am keenly aware of the problem, and it's not external in most cases. It's internal.
