I’ve been exactly in your situation before and I can say, without a hint of facetiousness, having kids does wonders in your thought life in this regard. It really “separates the wheat from the chaff” in a sense, mostly through neccessity. It’s not the reason I had kids of course and it’s not that other things aren’t important to me anymore but I ended up scraping to keep 1 or 2 things in front of me and then not really having the capacity to feel badly for the rest, you just get to them when it makes sense to do so.
Obviously you can't just snap your fingers and have a soul mate bearing cherubs appear in front of you but, I just thought I share my experience none-the-less.
Thanks for yours!
