Feeling Stuck in Career Growth

Anyone ever get that "I need to be doing something else/ something better/ something more" feeling? I like my job and me and my partner are doing decent overall. I've had a lot of growth even though I don't have a degree but every few months I feel like I just HAVE to learn something to be better. I've thought of taking classes, or doing bootcamps, but it always feels like a desperate need vs something I really want. The other problem is, even if I try it, ADHD makes me lose an agency to do anything that's just for me. If it's work related, I'm all in, but the second it's for my betterment, it won't get done. It takes me months to do basic things like change a toilet seat or mop the floors. I feel like attempting classes is a recipe for failure.
