GLC1968, thanks for taking the chance and putting your dreams out like this. Clearly you've touched a nerve and have quite a bit of company.
I'm sort of in a mix between what you're talking about and what Tulip voiced - while I've been mostly satisfied with my career/job choices up til this point I'm starting to really be in touch with the fact that it is not going to keep me engaged and satisfied for much longer. I have no big qualms about the idea of going back to school at (almost) 42, though the finances and "will I really like it?" worries do exist. I did some research before the holidays, and I've got a lot of work to do about exploring what's next and this thread is inspiring me to take the next step again.
I'm a little more concerned about dissatisfaction in other areas in my life. I didn't so much dream of Paris, but I definitely need to work on the "get happier" part. I'm feeling deeply drawn towards living more authentically. Should be quite a journey!
