You sound like my middle brother. He never got a degree either (he's nearly 72), went into the Air Force (1960's) and they taught him what became his computer skills plus working his way up in tech businesses (old Sperry/Univac). He had a great career and did as well or better than the rest of us. My other two brothers and myself and stepsister all got degrees and are all "ourselves". My oldest brother, nine years older than I am, got his degree the same year I got mine (so 9 years "late"). I changed my degree my senior year of college and got a degree in another major. When I was 50 (2000 :-) I had the pretend-I'm-85/at-the-end-of-my-life-what-will-I-regret talk with myself and realized I still loved the major I had originally and had changed out of when I was 20 because I was afraid. I was no longer afraid so went back and got a second degree in what I was "supposed" to. Like you, I had been taking classes since I left school so getting that second degree was not as bad as I thought it would be. I got it at a wholly online university (University of Maryland University College: Accredited Online College | UMUC ) and it took me 5-6 more years but has been well worth it to me because it was what I wanted. Maybe take another course or two to see if that sort of thing would be what you want?

Who cares if you can see how it might help you; you can't really know if it will help or not. You might meet classmates or professors who want to team up with you and offer you a different, better opportunities, you can't know? You might make connections who want to give business to your company and get promoted or whatever because of that where you are? It might just give you ideas, help you do your current job better.
