Maybe I define my self worth outside of my profession. In that case, I wouldn't see additional professional skills as self improvement. If anything, it would be even more of a reason to quit.
Don't you think there are a lot of worthwhile, "non-professional" skills to learn as well? I recently read an article about a programmer who learned woodworking, and summarily quit his job to be a woodworker in some rural area, and loved it!
I'm sure there's a lot out there that might interest you, that could turn into a profession you actually enjoy. Just a thought :)
