I am one of the person who, if they got 40 mil USD tomorrow, would just work much harder on stuff I like to work on (which is making open source software sustainable in robotics), because I would have to spend less time have to take care about the economics of daily life. I could get a chef to cook me personalized healthy meals. I could have a mini-gym at home (which is not that expensive to be honest).

but I could get a home near a major airport like 10 mins from SFO, and so with working out and eating consuming 4 hours and sleeping 6 hours a day and 2 hour of spouse time. I legit have 12 hours a day to work everyday. I could easily do that in a sustainable manner 6 days a week, and spending Sunday relaxing by helping out in my parent's farm and then relaxing in the evening before going back to work next week.

Seems like an ideal life for me. The only difference from today is the extra 3 hours I spend in traffic and an average 1 hour daily in running errands. And extra work on Saturday like fetching groceries, looking after my home, fixing stuff etc.

If I get money, I could save that 4 hour of my life and dedicate it to working on something I really like.

It's one out of a sea of options. Of course, not all are good and healthy. But some are.
