I posted this in response to a comment on my previous post - I want to save my thoughts for future reference and haven't figured out how to save comments in PDF without saving every single post with comments on it, so I'm posting my thoughts here.
Just to explain why I don't know if it (this internal position) will ultimately get me toward something I'll truly enjoy - it's an oil and gas property manager position. I can almost guarantee it doesn't involve books, writing or research in any form! If I'm considering going back to school for a master's in library science, I can't see that becoming an oil and gas property manager isn't going to further any goal that would go along with that degree. And it certainly won't use my law degree - you don't even have to have a law degree to be considered, just experience in my current position (which also doesn't require a law degree, but you wouldn't know that from the job postings for the position I now hold).
A month ago, two months ago, just being a breath of fresh air, being anywhere other than where I am, would have been enough. But I think that's a big part of the reason why I've ended up in the stinkhole I'm in now - always jumping to what seemed like a better deal at the time, without any kind of long-term career path or goal in mind. I'm almost 40, I'm getting too old to keep making that mistake. It's time for me to really think about what I want, and try to find something that makes me happy and that I can make a career of. I'm getting too old to keep job-hopping every three or four years.
