The "exploiting edges on your own" thing is a great point and I like it a lot, but there's also something to be said for always trying to have one "tentpole" element in your life which is a reliable bright spot, even if other elements of your life are chaotic/problematic/in flux etc.
This could be different elements at different times, e.g. you could lean really heavily on a friend group for a couple years, then later become religious and let your Church be your life's Northstar for a while as the friend group organically scatters, then later go deep with your family, or a sport, or travel, or whatever.
Right now it seems like your job is probably filling that "reliable bright spot" role in your life, and imho it's not worth discarding that until another independent element is clearly ready to fill that "bright spot" role.
