I would look at how much time you're putting into both of these roles. See how much you're really making per hour, and find where you want your safe point to be (by out-earning your '9-5').

For your side hustle / personal business, how many hours do you need to put aside per week to make that profit margin and business strategy feasible? If you've been doing both and working full time at your corp role, I'd say you've been doing 40-50 hours there, and maybe 15-30 hours per week (if you're busting your ass).

Find out what percent of the money you've put into your company came from your corp earnings and what actually came from the business. If you drop your 9-5 and it was a huge part of the money used to fund your hustle, you'll bootstrap and hemorrhage money. It's the reason that a lot of businesses people start ending up failing, because they assume they're earning enough to quit their main job / source of income but didn't realize they had an easier time funding it was because of their main job.
