If infinite wishes isn't an option:
1. The ability to automatically know the answer to any question I asked myself (so I could know everything without blowing my mind).
2. Immunity to the corruption of wealth, fame, and sleazy acquaintances.
3. Celebrity status.
Immune to the ethical corruption spread by "The Man", I would use my wishes to become a force for good.
I would use my special power to obtain the wealth necessary to accomplish my goals ("Hey Bricknave, how do I make a million dollars?" "First you [REDACTED] and then you [REDACTED]." "Oh, okay, thanks!"). I would use my celebrity status to teach people the importance of critical thinking skills, so they would be resistant to sensationalist misinformation spewed by con artists and idiots. If I enter politics, I would use my gifts to assist me in my campaign against that which makes life worse for the middle class and the lower class. I would also do my best to help Science thrive in America, for the sake of furthering Humanity.
