Great post - really enjoyed reading it. It was interesting to read the view that a new location won't automatically bring happiness. I think so many people look for an alternative or way out (I'm no different) but it is more a change in mindset that's required rather than a change in location.
I've certainly found that since having a more flexible working arrangement I've ended up putting more hours in too. The idea of scheduling free time for leisure sounds counter-intuitive but I can see it being an important way to find more of a balance.
