Unsurprisingly people here are telling to double down on following your ideas.
Such attitude is very effective at creating burnout.
I do work because I like it (and, unsurprisingly, the things that are most likeable are the least profitable or practical). And I don't do it at an unsustainable pace, which anything you're trying to profit from inherently demands. And the only way to profit in software is to pin your users down to a table and give them a night of value extraction they'll never forget. You also have to work with cringe technologies, like web tech. Money is the root of all evil to me, and being obsessed with it seems unhealthy af and a disgusting basis for technological curiosity/craft.
Are you sure you understand what burnout really is?

Yeah, that sounds like burnout all right. But don't ask HN, ask a therapist.
