Telekinesis.
I wouldn't have to worry about putting gas in my car ever again. Put it in neutral and telekinesis myself down the freeway.
I could fetch drinks from downstairs without getting up. I could become a superhero and fight crime.
I could pull awesome pranks. I could act like a magician only I would be using telekinesis for real instead of it being an illusion, and no one would know. I could fetch drinks from downstairs without getting up.
