How to transition into Entrepreneurship?

I am currently a full-stack developer with 6 years of experience. Lately I've been working a lot with AI however I feel like this is not the path I want to take. I really want to go full entrepreneurship route and create actual business.

I do feel like hackernews community is more on a business spectrum compared to other developer communities.

I am already quitting my job in September and I don't really have anything lined up after it. I'm just too burnt out / stressed out currently at my job.

Ideally I want to just build stuff and make business out of it, however realistically I understand that I need some supplemental income and that would require me to find another developer job.

Do you have any advices for me?
