A wish that can't be spoiled? no such thing
eg, you get your BB code perfect every time, but start paraphrasing it in real life and so become a social outcast because you can't communicate appropriately
world peace, aliens invade, enslave/kill us yadayada
srsly you need to better than that
I wish I didn't have an ingrown toenail (ewwww, and owwww all at the same time)
