Travel. I'm someone who likes to move a lot, so if money wasn't a problem, I'd probably be on the road. Eventually, if money still continued being plentiful I'd pretty much do the same things I'm doing now. Write. Yoga and dance and things that make me happy. Hang out with people who matter. It's a boring answer, but still.
I think you make a very valid point about this low standards argument. I know enough women with impossible standards who are constantly miserable. And as you say, it's one thing to have really low standards and not recognize that you deserve to be treated with a bare minimum of courtesy and decency, and quite another to find joy in little things someone does to help you or make you smile. That's where the main chunk of happiness is at. :)
How is it boring if it's what you enjoy? It shouldn't matter whether others perceive it as interesting or exciting. I think travel is something a lot of people would do much more of if they could. It's an adventure in itself, always something new to experience and learn.
