I think the only thing I'd change about my current living situation is to uproot the entire house and backyard and drop it on a beach. Preferably on a beach in a foreign country.
A warm foreign country.
With a good economy and cheap beer.
Cheap, delicious, cold beer.
And Mexican food!

Plus a good internet signal and a nearby bookstore where the books are in English and are books I want to read.
Also there should be reptiles in this country. Or really cool animals like they have in Madagascar. But no violence or rainforest destruction.
Oo! And freedom! Freedom would be nice. Democratic governmental institutions with a great big heaping pile of Freedom on top.
Did I mention the beer?
