Wish

If I could have one thing one wish, would I have the courage to wish for something to benefit the world? Something for the greater good of humanity? Or would I just wish for something I want something that's mine? Would I regret making a selfless wish? I know I would, every time I would use what I wanted I would regret not having it I'd be angry. But would I feel guilty wishing for something that's mine. I know I would every single time it benefited me or every single time someone else could have used my wish.
