Granted, you become a super genius but like so many super geniuses you have been become insane and just outright crazy. You lose your friends and your family. Your back begins to ache and your eyesight goes and before you know it, you're stuck in a wheelchair for the rest of your life lacking the ability to talk.
I wish I made a wish before hand because wishing is really good therefore I wish for a wish and that makes one great wish.
