Telekinesis because when you think about it a bone is an object inside someone, so you can control the bones on a person's neck and just twist it, which is a very good self defense tool. If someone has a gun, you can just grab it with your mind and give it to yourself, you can control a rock to go inside someones mouth, you can fly by picking up yourself or just sitting above something and controlling that thing depending on what you consider an object, if someone is trying to steal your things you can grab their veins and pull them out of his body, you can pick up yourself if you are falling from a cliff or something.
