> From it I ascertained that the first two questions one should ask are when encountering something in life are, "is this actually important?" and "is this a problem I can actually solve or make a meaningful difference in helping solve?" - anything one can answer "no" to either of those questions one should just let go of, and try to focus one's energies on other problems.

This puts succinctly something I try to practice that I likely got from the same source. My parents were both in AA for the entire time I knew them and I was carried along to many meetings and, later, went along with them of my own volition. I have a great respect for the organization and, especially, the people humble enough to recognize their need for support.
