Since I can't wish for more wishes, I would wish for another Lamp with a Genie inside every third wish. It is an endless amount of wishing, in order to counter the means of other people who actually think that wishing for everyone to have every good emotion to occur without the bad opposites will actually bring said emotion.

On that note, I wouldn't wish for anything. If I can't walk the distance to get it myself, then it's not worth aiming for. Especially world peace or general happiness; what a absolutely useless concept. If you did that, then it would just introduce a paradox within the world system, and happiness as one would know it would disappear, and sufferring would reintroduce itself into the world. You wouldn't necessarily have happiness, nor is happiness defined the same for everyone.
