By home business you mean Joy being our DM?
Takamuwu, you haven't been paying attention but that's okay, I can set you straight.
Bear has a STEM day job but he also has a home business that he works with his business partner 50/50 and several others who work part time to full time with him, the same 4 that are involved with him and the resort they go to the last 3 years, exgf, exgf sister, bestiemom, the narcissist, and his business partner (all women). He personally makes about the same from his STEM and the amount he's paid in the personal business. Of them all, he would say his business partner is mist important but his customers say he is hands down. Without him, the business would continue but it would definitely lose the magic that makes it fun.
He also does what he calls side hustles in the last few summers, this year he's probably not going to because along with his kitchen, he did one where it took him 10 months and that's just too much.
Joy's work is just how Bear system has fun. Bear doesn't go on vacation or take a day off, he feels awful when he does, it's just the way he is. Give him 2 hours unassigned and he becomes incredibly bored. Workaholic? Not really, he just feels the sense of urgency. He wants to be self-sufficient if he ever lost his jobs. It's probably there so now it's a matter of quality of life if things turn south.
Writing, DnD, single player casual games, working out, that's what he does for fun, that's now what we do and think about constantly and we've never been happier.
He also has plans for the garden and his truck, but that's not really "for fun" more like for a sense of accomplishment or for other reasons.
He's been hustling non-stop since 2014 or so, since college really, he got two masters while working full time, he enjoys his life, it's been a long haul and he's come a long way.
In terms of the future, he has already fulfilled everything he wanted to do. He never wanted kids and marriage would have to work for him, not the other way around so that's really just achievement hunting and not something he cares about. Ask again in 5 years.
The surgeon said rest, he says he can do work while resting.
