To be honest, I kind of fell into my career. It wasn't a conscious choice. Now, that being said, I think that subconsciously, over the years I've made choices that have led me to this exact place.
Was there anything about your previous career that you enjoyed? From the career paths the Myers-Brigg suggested for you, I would gather that you're an independent go-getter? Just throwing ideas out, but what about hiring yourself out as a consultant in an IT-related field? For instance, I just went off on my own for the first time (after having worked for large companies my whole career). I hired a CPA to teach me Quickbooks (paid him $100/hr, and it was the best couple hundred dollars I've spent in a very long time!). This CPA is a "CFO for hire" in whatever capacity you need him - a friend of mine hires this guy to do his books from top to bottom every month - keep track of bills, pay the bills, balance the corporate checkbook. I am in a more hands-on field, so I hired this guy just to teach me how to do it myself, and serve as an hourly consultant when I need him. WHAT IF you did something like that, but with IT? When somebody like me gets a computer virus and doesn't know what to do, I could pick up the phone and call you. Or when I need to figure out how to get my printer onto my wireless network... or when I need to purchase new software and I need someone to research it for me. I think there is probably a call for consultants with specialized abilities like IT, accounting, HR, and the like. The benefit for you would be calling your own shots, being the boss, and having a flexible schedule. Obviously the downside is that working for yourself is somewhat unpredictable. If you're the type of person who can handle it, it may be a good avenue for you though. Just my thoughts!
