Unrealistically... enough money that I didn't have to worry and could afford my own, small (1000-1200 sqft) house with a garage and a little garden and new things instead of old, "preowned" housewares and clothes.
Realistically... a hot water heater than could always supply hot water.
Well, okay, I live in an apartment so that's still not realistic either. How about a place where rent doesn't increase by $30-50/month every year without having to go back to a place where my neighbors got in fights in the hallway. Seriously, though, I'd love hot water that I could have and use whenever I wanted.
An outdoor private hot tub with a view of the sky, preferably draining into an inground pool, and a deep-tissue masseuse who comes at least once daily. At least I'd be happy and loose when I confronted the rest of life's issues!!!
