Doesn’t have to be a thing you bought. Just some thing you didn’t have but then once you did it expanded your scope of actions.
The first obvious example that comes to mind is a car. Plenty of drawbacks to prevalence of cars, but being able to go where I want when I want, and far away, is very transformative.
I’m interested in other examples of things that aren’t just useful, but that open new possibilities.
My divorce. I didn’t even realize that my ex-wife was abusive until getting into the divorce process. Once I got away and started to understand, I began to take some of my power back and develop even more. I went from terrified of her to strong and confident.
I hope your new positive path continues. Good luck, said the survivor or a bad marriage.
