If magic was real, I would practice it every day. I would go to work, come home, write, cook, clean, do my laundry, and then sometimes when I felt the urge coming on, I would practice magic. It wouldn't be much, at least to start out with. A little levitation here and there, maybe some telekinesis. I think it would take a while to learn it, but I have always wondered about teleportation.
If magic was real, I wouldn't have to go to work, but I would anyway. I would get there on time, even if I slept in, because I'd be a bit savvy with the space-time continuum. I'd practice a little healing, a little empathy, a bit of calming of the nerves. I would offer my magic as a free service to those who need it the most. At least I think that's what I'd do.
If magic was real, I would be able to fly.
If magic was real, I would shapeshift as often as possible, and learn how to become any animal I ever dreamed of becoming. Oh and I would also talk to animals.
If magic was real, there would be no poverty, no war, no disease, no inequality, no oppression. Everyone would be given equal access to services, and the world would be a better place.
If magic was real, I would still read fantasy and sci fi books. I would try to write them too, although I would have an unfair advantage. Would everyone be able to do magic, if magic was real? Could I gift it to others? Would I gift it to all? What if I could only bestow magic on one hundred people before my power was drained completely? Would I still share it?
If magic was real, would Donald Trump be able to, like, do magic? How would we stop him?
If magic was real, I am pretty sure that there would be a lot more chaos in the world before there was order, but that's also kind of a good thing.
Would there be dragons?
Would anyone need cars?
Would we be able to save the planet then?
Would anyone care?
