Assuming ‘complete authority’ means what I hope it means, I’d immediately install myself as dictator of the US and set this nation on the right course.

(face turns red)
PFFFFF!
(wild, maniacal cackling)
Also, I’d release all nonviolent offenders, abolish the death penalty (yes, even for terrorists), legalize a lot of things, subsidize secondary education a lot more than we’re doing now, trim our military down a bit, return a bit of power to the individual state and really push for stricter environmental laws.
I would also give education a big kick in the pants–and I believe this should be mostly regulated by the federal government, with minimal state involvement. The current state of the American school is grim and the quality of education that one can get in, say, Heehawbumblevilleton, Tennessee, is a lot worse than in a larger city with better funding. I’d like to even out the quality of our schools to allow a trapped genius like myself to be better prepared for a job that doesn’t involve coveralls and a balding, overweight boss named Murray.
And I’d put the White House on gimbals. No good reason; I think it’d be funny.
