I have been struggling with this same question for the past few years, and especially the past year or so.
I hate the industry I am in, but a lot of that is from a previous job in it; my current job is at least tolerable, but it is difficult to shake the burnout/anxiety from the previous experiences. The hours are reasonable and the pay is enough that I will likely be taking a massive pay cut no matter what I do next, and I am cognizant on a pay-per-hour basis I will probably never make this much again once I leave. On most days I don't have to work too hard, though things can get very stressful on occasion (a lot of the stress is probably self-imposed though). I get some comfort from knowing that I have one foot out of the door from this industry, so to speak, and that I am at least financially secure, if not FI.
I am something like 2.5-3 years from being borderline FI were I to stay in this job, however the thought of staying that long makes my stomach sink. I have had a fairly frugal lifestyle even before discovering MMM, so I could take a large pay cut and still cover my expenses; reaching FI would obviously be delayed longer though.
I imagine I would enjoy the scenic route, but there is probably fear on some level that doing this would fail, and that I would have to come back to the same industry in a worse position.
