Recent life change you made with "why didn't I do this earlier" vibes?

Probably not what you're looking for, but for me it was: dumping my now ex girlfriend, getting out of that one-way, toxic relationship and start focusing on myself. Like, making an explicit active effort to focus on myself.

I wish I had wasted less time on that relationship but better late than never I guess.

Being able to focus on myself allowed me to start sorting out some sides of my life, like getting back in a decent shape: I lost almost 9 kilograms (about 18 pounds, i think) over the last year (pure diet, no ozempic/semaglutide involved) and I now like myself when I see myself in the mirror.

I'm now slowly starting to look back to all those ideas, small and big, I had put away over the years.

Consequentially, another something I wonder why I didn't do sooner: having much, much higher standards in terms of women I give my attention to. I much prefer being on my own but at peace than spending time with somebody that makes me wish I was alone. I'm not a twenty-something anymore and I'm overall okay with being on my own (as in, not in a relationship) for a while.

Maybe one day I'll fall in love again, maybe not. So far I'm not really thinking about it, and it's going overall well.

When I was diagnosed with Parkinson's Disease, they started giving me dopamine supplements (carbidopa-levodopa). Now, all of a sudden, I'm getting things done after spending most of my life vegetating lacking the motivation to do more than get by. I insist that it is not the disease that has motivated me. Remarkable improvements in lifestyles are known when folks are given carbidopa-levodopa. Were there relic Puritanical values that led society to keep this away from me or just lack of understanding? I don't know, but it does seem a pity as I can't do anything about it now. Others might consider this as a strategy to improve their lifestyle. For those with ADHD like myself who never got much from Ritalin, this might be especially worth considering.
