Have A Weird Or Unusual Dream

If you could get revenge on anyone, who would it be? How would you go about doing it?

Ok so here is my question. Say you died and God was too busy to deal with you so he is like "do what ever you want". Now you can be reborn into another world and can increase any stats you want knowledge in specific places like medicine, war , etc. Beauty, strength, you get it.

Which world would you be reborn in and what stats would you increase?

I would totally go to those worlds where you get married to a prince and both of you have to work to become emperor and empress as for stats i would increase all cause i am a dumbass, ugly, bitch.
