I had a very similar experience. I had a degree, didn’t do anything with it. Got a cheap certificate and it got me into a good admin job. Since then I’ve done absolutely nothing to do with my actual degree but it works great when applying for internal positions for upward mobility because I check the “has degree” box.

That being said, I absolutely loved my college/university experience and wouldn’t trade it for the world. While I don’t think anything that I learned in the curriculum helped me significantly, everything else I learned has.
