It looks to me like it's not especially fruitful to agonize over questions like, "Am I satisfied with my life as it is?"
All of us can think of things we are satisfied with and things we aren't. For most of us, the mix varies widely over the course of time, and the causes of the variation are usually both objective and subjective.
If we are in a "good mood", we tend to be in denial about the bad things and engage in wishful thinking about the bad things; if we are in a "bad mood", we may exaggerate the negative aspects of our life and skip over the good aspects.
So isn't it better to consciously direct any soul-searching we do in more constructive directions?
In other words, shouldn't we be asking ourselves,
"What can I do to minimize the bad elements in my life and maximize the good ones?"
