I do hope all turns out well and you don't have the infamous worms on the brain or something worse LOL. Seriously, RFK brain worm infestation aside, I hope all is well.
Occasionally I will look back with some regrets, but like you I dismiss it. I tell myself I did the best I could with the experience and knowledge I had at the time. As far as work, I am medically retired now so stopped working before I wanted to. Luckily the earlier life and career choices I made, helped make that possible. I enjoy this involuntary retirement the best I can under the conditions.
