> but really I've internalized the idea that everyone is living a life less than what they hoped their life would be to various extents and that there is also a near infinite combination of ways to achieve this effect such that no one can be dismissed for their misery in any respect without also dismissing the "legitimate" misery of a wide swath of people.

There's a downside to this logic, one of the enabling sort. I consider myself fairly empathetic, but with a very pragmatic tint. I find many, many people take on complaining and a victim/underdog status with an almost hobby-like approach. And I watch how others react, which is exactly as expected: sympathy, attention, allowing those complainers a way out of personal responsibility or true introspection (specifically into their role in managing reactions to external events). It's a never ending cycle. And it hardly ever promotes growth. And almost never results in true happiness (happiness is probably the wrong word...maybe contentedness is better, tho maybe not).

So, the same way you wonder about those people who "dismiss others' concerns," I wonder about those who kowtow to others' words and fail to consider the reality (perceived, of course) behind them. It often feels lazy to me. And short-term thinking. Truly caring about another person sometimes means forsaking short-term "feel goods" for long term growth.
