Many roads with the same destination. Best of luck to you man. I think regardless you're in a good spot with age 65 looming. Just keep in mind that 5 years of doing something you really don't like to get to a major is a soul sucking endeavor. Most of us have done exactly that to get where we are. My best suggestion is finding somewhere palatable that will lead you to your goal instead of hating life to get there faster.
