If you're already making revenue, it will be easier to scale up than if you had no revenue at all. So quitting your day job doesn't sound too bad, in the short-term. If your project fails, you'll have gained experience and live a few exhilarating years working for yourself, but your savings will be gone.
Taking a perspective that stretches further in time, it sounds like you're on your way to reach financial independence fairly soon, assuming you don't quit your job just yet. tldr: if you save enough money and invest it intelligently (basically in the s&p 500 or a total stock market), you should be able to live off the compounding interests of your investments. If you have 5 years of expenses already saved up, you might be a quarter/third of the way to reach your number (the amount invested for which you don't need to work anymore). Finally, having a goal laid as such might make it easier to bear your day job until you can retire in a few years.
For more info, check out the book Financial Freedom. I didn't write it but I'm in the same boat as you, so my goal is now to make and invest as much money as possible through day job and side hustles, to then be able to retire and work because I want to, rather than because I need to.
