I can relate. It's sort of "Hell is other people." I work very effectively on my own, but the scope is limited. Big things require teams.
I realize how fortunate I am, that I could afford to retire. I don't have as much money as I would, with another ten years under my belt, but I should be OK.
It absolutely stuns me, that young folks are getting paid more out of school, than I made, in my entire career, and have less to show for it.
