First, I'd wish that I can change the rules about what I can and cannot wish about.
Second, I'd wish that the rule against wishing for more wishes would be erased.
Third, I'd wish for more wishes.
I know someone else wished for 700 more genies:
1. A private island.
2. Superpowers.
3. 700 more genies.
but... genies are total drama queens. They also like twisting your words around a lot, so I think once I have infinite wishes, I'd spend the first few dozen, or hundred, making sure that everything is interpreted exactly as I intend it to be (when making wishes. Non-wish things I say shouldn't be affected).
