Willard,
You're in your peak earning years, assuming you are using your degree in a reasonably remunerative job, which it sounds like. Why leave those years behind for a financially risky career? You would, at most, have 10 years of, mostly, lowish pay, probably far below what you are earning now for most of those years. Now, is when you be saving for retirement.
OTOH, if you have a couple of million saved, disregard.
