There are plenty of things I could have done differently/better in life, but all in all I think most of them have taught me things, or led me to other places that have turned out ok, so I can't really regret them overall.
This.
If I'd have done a different uni degree would I have met the same people later?
If I'd had more confidence would I have stayed in this country or settled in Australia as I'd planned to and never met DH?
If I'd have had a better career would I have had DS?
If I'd still had DS would I have coped with a career and homeschooling during lockdown and found the last 12 months unbelievably difficult? Would we have been financially screwed by me being furloughed/redundant/quit due to covid as we'd have stretched ourselves further?
Its a hard one, because the things I value most and appreciate most have been part of a chain reaction of events. If things had 'gone better' earlier in my life, I'm not convinced that my life would be better and I'd be happier. I'd just have different pressures and different regrets.
I think I have to view things in the context of appreciating and love what I do have rather than laminating how things could have been different. Ultimately I'm secure financially, have an awesome DH and DS and life isn't so bad when all is said and done. I could have been a superstar or a groundbreaking scientist or travelling the world or have won the lottery etc etc, but would my life really be better?
The grass is greener mentality isn't particularly helpful - we assume things would be better without considering if we had made 'the right choices' in the long run that could have fucked up our lives even more and the regrets we do have would pale in comparision to our alternative universe selves. Ultimately what we regret teaches us valuable lessons and stop us making bigger ones in the future... And even if we have fucked up, in many cases we could have fucked up even worse.
