I would absolutely change nothing. You see, when everything's perfect, everything's boring. It doesn't leave much space for variance. Perfection destroys the possibility of individual differences or preferences. All perfect entities are the same. All imperfect entities are different in their own way. Or, as Aristotle put it:
Quote:
Again, it is possible to fail in many ways (for evil belongs to the class of the unlimited, as the Pythagoreans conjectured, and good to that of the limited), while to succeed is possible only in one way (for which reason also one is easy and the other difficult -- to miss the mark easy, to hit it difficult); for these reasons also, then, excess and defect are characteristic of vice, and the mean of virtue; For men are good in but one way, but bad in many.
I think I would change things that cause me sorrow or grief. Sure, I can change my thoughts about those things, but it would seem nicer and more interesting to *swap* these things not through my thoughts but through my special, higher powers :3
Absolutely nothing. Just give humans the right to think and let them do what they want. You cant save people from their own stupidity. Cant kill them because they are your people. You cant keep proving you exist because the minute you arent there people will think they just had heartburn. So literally, all i would do it allow the world to continue as how it has been continuing and let humans and animals learn to think for themselves.
I would eliminate man buns, Snapchat, people that have something against Israel, pineapple on pizza, and Olive Garden. I would give America real Italian restaurants, and I would make everyone buy Katy Perry's discography, bringing peace to the world.
