If somehow you knew everything in the world, and you were the only person who did, would you tell anybody or would you keep it to yourself? Would you decide to rule the world with this incredible power, or would you just use it on a smaller scale?
Tell the world! Bow before me!
Keep it to myself. Who knows what would happen if I said anything
Keep it to myself and use it to secretly troll people
Open up a psychic hotline/advice line and use my power to make a living

Ignore it/act like nothing happened
Go crazy
Tell/use it to help friends and family, but nothing more than that
