Assuming not too much else changes (we can still live in a house and pursue whatever interests and activities) there's so much stuff we would love to be doing instead of this "working for a living" crap.
Working for a living sucks but, so does doing nothing for a life, in my opinion. I would have absolutely no trouble finding things to do with my life I find rewarding however, I predict people overestimate their own abilities to do so.
When transitioning to homeschooling from traditional schooling, a period of deschooling usually happens:
or in a nutshell "relax and don't do much for a little while". I don't have any experience with this as none of my kids ever went to school, I have heard/read recommendations of 1 month for every year the child has been at school. Guess some would take more or less time depending on the person. It doesn't seem too far a stretch that any given adult used to a 9-5 office job with possible insane overtime who suddenly gets dropped would undergo a similar process. If the rough guideline of 1 month for each year spent in the workforce is applied it wouldn't be too surprising for some people to spend a year or so being a lazy mass consumer before finally getting around to doing all of those things that they said they wanted to do :)
