It's certainly not a new problem. Entire books have been written about a supposed "work/life" balance, philosophers have debated forever and a day, and parents sit back at the end of every day and wonder "WTF". We're cursed, as humans, to be aware of our own mortality and for some reason have a desire to "do something" before our time runs out. There's also societal and economic pressures that we just can't seem to divorce ourselves from.
Everyone takes their own approach to happiness. Mine is to work hard during the week (job, kids, school, house chores, etc) and then enjoy the weekend to the fullest. Sometimes it works, sometimes it doesn't, but it often balances out over a longer term. More play is a good thing.
As long as there's healthy happiness! And I like the statement of "we're cursed", it's simple and accurate to describe humans in a nutshell...being sentient isn't a perfect thing after all.
Your method looks pretty well :) normally I take very frequent breaks instead of cramming the fun into two days, and of course it doesn't work all the time...but like yours it often balances out once it reaches the extreme!
Sometimes I think I'd like to be my dog. It's an enjoyable thought to think that I was a dog in a prior life. :) All she wants to do is be with me, play, and let me feed her. Obviously she's not a wild, untamed creature in the wild having to hunt or scavenge for food, but she's certainly in tune with what she likes!
Heh, sometimes I also sit at the door looking at the dog of the house...her life is too simple for us to deem boring. When there's nothing to do, she sleeps; and when it's time, food is there. But she also seem to enjoy life...haha.
