You should be getting advice from people who have failed AND succeeded. If the person only failed and never succeeded in anything, they probably think they know why they failed but actually they don't. That's why you see a lot of misleading medium blog posts about people talking about why they failed when they know nothing about why. On the other hand people who've only succeeded (has nothing to do with whether they're more competent than the ones who've failed, just means they were lucky) don't know what it means to fail so won't be able to give you good advice.

Secondly, raising money is not related to succeeding. You will understand when you take a step back and watch 99% of the once-popular companies go out of business after raising millions of dollars.

I suggest you keep working on your thing on the side (if you're still passionate about it) and get a job. You can always quit and come back to fulltime on your thing when you see a glimmer of hope.
