Well, shit, then. "Happiness" becomes the only feasible answer, I think, because absolutely anything else becomes completely arbitrary. Sure, you might keep your camera because you think it predisposes you to a place where you could own one, but maybe you nicked it off some hapless tourist, and someone else in the ghetto will see you with it and shiv you for it. You might get a great education, but only because the horrific deaths of your family members got you workers comp to pay for it, or you might be bitter. Your new perceptions and reasoning would probably be entirely different, so you couldn't guarantee any particular capacity for knowledge or common sense or anything. Your bew preferences would likely render any other choice you make irrelevant.
So basically, the question is "Imagine what would happen if someone else magically had the memory of your life transplanted into their brain. Also, they get your cat."
