Not quite answering your question, but I quit my great tech job and decided to burn my savings and go into debt by going to law school. At least consider that maybe it's not the 9-5 that's the problem, but the line of work itself. Being good at something doesn't mean you're passionate or motivated for it. Depending on the kind of person you are, lack of passion/motivation can be an insurmountable obstacle to being the best you can be, to being fulfilled by your work.
