I would make everyone intrinsically good, to encourage a faster pace toward an effective utopia without all the risk of screwing up the equation. Things would eventually sort out to that end, but far faster.
I would then create a free easily searchable compendium of the totality of scientific knowledge. Every property of every material, every reaction, every particle, every mathematical equation to describe every phenomenon. Nothing would be missing.
I would then do the same for the sum of human history, but it would update itself as time passed, to always be current.
I would then grant everyone full understanding of a universal language, in which these compendiums would be written. Individual languages would still exist but the universal language would be understood everywhere by everyone.
I'd give everyone the gift of flight, Neo-style.
Finally, everyone on the planet, including myself, would then sleep the most relaxing, rehabilitating, perfect sleep of our lives, in comfort and safety, until my power went away.
(I'd also pay off all my debts, get a sweet car, restore my motorcycle to mint condition, and grant myself perfect health. Oh, and invincibility and immortality, with the option to die at a time of my choosing.
