You’re not alone. I spent the better part of my 30s lamenting the 10 wasted years (thanks undiagnosed ADHD) and thousands of dollars of crushing debt that totally useless piece of paper cost me.
I don’t give two shits if my kids go to college or not, but I’m sure as shit not paying for it if they do. I can’t. I do, however, care that they do SOMETHING after high school that isn’t kicking back on my couch smoking weed and eating chips. Be it trade school, OJT, travel, or college I do insist they learn and grow after graduation.
FWIW, what helped me make peace with my wasted college experience is twofold. First, someone I trusted explained that what a degree--any degree--showed employers was that you were able to complete something long term, extensive, etc. No matter how useless that thing you completed actually was. (Okay, i hate everything marginally less than before.) The second was that since we had refinanced our home and rolled my student loans into the refi, and my ex had to deal with selling the house in the divorce (lost money, we were upside down), I never had to make another student loan payment and it pissed him off to no end so that was worth it.
Kinda great, since in every possible other way, he screwed me big time.
