If I were you, I'd do the following: live frugally and continue your career until you reach a point where you can safely and comfortably retire. Look into FIRE (financial independence, retire early) communities and resources for more info. Once you reach that point, do whatever you want because the money no longer matters. Especially if you are okay with your current job, I personally wouldn't throw such a great position away just to gamble on a personal business. If it's really consuming you that much, just do it on the side. If you can't keep up your current job and get your business started in your free time, I personally don't think you'll have what it takes to power through the business anyway.
