The fact that you are replying to the comments about how to make progress and keep coding, while not replying to some of the other kind of comments, is actually the biggest red flag. Coding is not going to be your biggest problem.

Of course, it's possible you'll get lost in the weeds of some framework or scaling something that you don't need. I can tell from your replies that you get this and you understand you have to ship. Let's assume you got that covered.

The real danger is that you will ship, and only then you will discover nobody wants to pay for what you built. From your pattern of replies, I suspect this is what is going to bite you, and it's why you shouldn't start with code at all and you shouldn't have any expectation of finding revenue before your savings run out.

Anyway, as others have said, whether you take the excellent advice here or not, either way you will learn a lot by trying!
