Hiya, this thread caught my attention as I have changed career several times over the last 12 years (aircraft mechanic in airforce, then pharmacy technician, now pilot). Also considering doing a random degree, part-time, starting next year (in history, just for fun). I have learnt over the years that as long as you have enough money to survive on, the best career is the one that makes you the happiest...cheesy but true

I also found that going back to study as an 'older' student I put in more effort & got more out of it - especially having to compete with sexist, pimply 18yo males for my flying quals!
Just wanted to say good luck with a decision Denny25, its a big step to take, but you will feel so much happier with yourself for it
