I'd really want to fly. Either that or teleport. This way I wouldn't have to worry about leaving places when I could instantly get back there.
However, flying is a serious passion of mine in my dreams. I am always fluid when I fly so I take note of how I fly. I usually fly my flapping my hands really fast and jumping and then I take off. However, momentum is poor so I struggle horizontally, but not vertically.
If I could at least fly like a bird, I'd love it. There are so many places I've wanted to see and go to by flying. I could fly across water, over people's backyards to see what's behind those fences, over private, gated rich areas, to Manhattan, to the top of the Statue of Liberty and even to simple places like roofs and decks.
As you can tell, I really have this thought through.
I'd love to fly.
