I wouldn't want to be invisible or be able to read minds. Flying might be cool, but it would undoubtedly be exhausting.
No, the one power I've always wanted, since I was a kid -- since I saw it on "My Favorite Martian" -- would be the power to point at something and make it come flying to you. I've dreamed about this so many times I even know how the weight affects the effort of levitating things.
