I'm in a similar (but different) position. I'll give you the advice my current boss gave me: keep your day job while you learn the skills needed to find another. Then keep your day job while you apply to jobs that are more aligned with your desired fulfillment. Once you are offered one of those jobs, quit your day job and transfer to the other.

In your case, where you want to start your own company, those are some grand ambitions. Be ready for disappointment, as that's not a path that works out for most people. But my boss's advice still applies to you: keep your day job and push through it while you work on building the infrastructure for your own company. Only once your company becomes profitable enough to pay the bills should you quit your day job. Because unfortunately, we live in a society that threatens everyone with homelessness, starvation, and death if the things that fulfill them are not producing something other people want enough of.
