> Stardew Valley is a weird example because the guy spent four and a half years working 12-hour days and did _everything_ themselves.. not sure that's the comparison you want here

That's exactly the comparison I want: he took his time and demonstrated that it can be done give the time available to us. If you can only give six hours, then I guess it would take eight years. There's also another lesson to be learnt here: don't do everything form scratch :P

> and their family/girlfriend supported them

I'd replace a girlfriend that doesn't support me; I'd disconnect from a family who doesn't support me.
