This time crunch is exacerbated even further when you're trying to bootstrap. 8 hour day job (at least) + at least 3 or 4 hours nightly trying to hustle your way through a product doesn't leave much time for sleep/breathing etc. let alone relaxing your mind in any substantive way. Plus the guilt you feel if you take a day off from the day job and don't spend that on what you're working on.

I'm trying to figure out better ways to maximize my time and squeeze the absolute most out of it, while maintaining some semblance of work/life balance. But it's a struggle, there's no doubt. There's the momentary victory of working out all of the scheduling but if you burn out, it's not worth much, is it?
