If you had any super power what would it be and why?

I always liked the ability to teleport myself and objects.

I think it'd be interesting, if I was late, teleport to a bathroom or something and walk out early. If I forgot something, I could teleport home to get it, also going home would be really quick since it's just a second away.
Hell, doing things like going out to do shopping would be quick, I'd just teleport easily.

Of course, not sure how it would work. Would I have to visualize the place? Need to calculate coordinates? Hell, would it even work if I wanted to say go to America without knowing any location in America.
