First off, thanks everyone for your individual inputs. I greatly appreciate the answers and really took the time to think things over.
I do agree now that going back is probably not the best idea. I DO have an interest in CS, and am not just looking for a well paying job. What some have suggested is to study/learn some software/'languages' to eventually become a business analyst, which is something that sounds what I'd like to do -- SQL, SAP, etc.
Now I just have to find some good resources to study in my free time. I will eventually have to be certified, but I'll come to that crossroad later. Any suggestions on the best way to get started on the learning process, say with SQL?
