What triggers my feelings of being powerless
Thought provoking list. A direction I would go with this is that when you recognize what you can't control, you can then set out toward solving the problem.
An easy example for me is the future of Social Security. It is in some measure of trouble, the consequences for that trouble are estimated to impact payouts in 2034.
Fixes that get talked about the most are reducing benefits, raising the retirement age (a de facto cut in benefits) and raising taxes. Another fix that is talked about less is means testing.
It is easy to see something is coming, I am powerless to alter that outcome so it is up to me to figure out my own solution.
