When I'm working on a personal project I'm really passionate about, my productivity is literally orders of magnitude higher than at any day job I've had. Months or years are compressed into days.
For any ambitious personal project that I'm intrinsically motivated by, I'm working on it and designing it pretty much every free moment I have. It's actually crazy to me how much I can get done if there's absolutely zero "ugh field" [1] inhibiting me. It doesn't feel like work at all. I'd happily take 20% of my current salary if it meant I could do that all day instead.
Even if it's stressful and even if I might fail miserably, I think life should be lived. If there's even the tiniest sliver of a chance that I could support myself just doing something like that, I know I'd be much happier. And if turning such a thing into a job or organization sucks the fun out of it, then I'll just keep trying again and again until I can find a project with a sufficiently viable enjoyment:financial stability ratio.
