Sorry for the typical, unoriginal advice thread.
BACKSTORY:
25 years old. Not married. I've spent the last 3 years working at a FAANG company - more or less right out of college. For the first 2.5 years I lived at home with my parents. As such, I've saved quite a bit. Now I'm living in the city. With recent changes to my team goals and product, I find myself extremely unfulfilled as of late. I now regularly engage in fantasies of quitting, and my gut tells me it's the right call.
I've always had personal projects I work on. Mostly ones that are intended to make a tiny bit of passive income. No one-hit wonders. But none of them have seen the light of day. I lose interest half way through. In my time off, I would like to finish one of them.
I'm somewhat risk averse, so I would only allow myself to go 6 months before trying to find another job (provided I can't come up with any solo income in that time). I hold no belief that I'll make a profitable project being solo. I don't fantasize about being a startup founder who makes millions. I just want some time to work on projects I enjoy. Maybe make some money off them. Probably not.
USEFUL INFO:
* Rent + everything else = ~4k a month. I can get that lower.
* I have 275k in savings. Not counting 401k.
* 6mo would cost about 25k.
* My lease is up for renew in 6mo, which is a nice coincidence.
* Got promoted in the last 6 months. This may help job prospects in the future - companies may more easily hire me at that level, than if I quit without getting promoted.
RISKS:
1) Sucking it up and working at this company the next 8 years would result in a very lucrative career, and that's a large opportunity cost.
2) Getting a job 6 months from now may not be as easy as I pretend it is. (What if the economy explodes!)
3) I may find that I have motivation for personal projects either, and live 6 months in a quiet depression in my underwear.
ALTERNATIVES:
1) I suck it up and do my job. People would love this job. It's cushy and it pays very well. Just do it for 5 more years and then consider this stuff.
2) Change teams at work. I imagine this might be only a mitigation, but maybe it would make things better.
3) Talk to my manager about working on stuff that I want to. I love to create and experiment. I know our problem area well now. I have things I want to create that would be valuable to the company that I would be passionate about. Would it be wise to ask for a 3 month trial of working on my own solo thing within the company? I would like that.
So what do you think? Should I do it?
It sounds like you want to take 6 months as a way to enjoy life before getting back to "the grind". Taking time off is good, but I'd think more about where you want to end up rather than just jumping back into the job market and trying to maximize your income again.
