∬ | "if manifestation is real, why don't you manifest world peace???"
why don't YOU manifest world peace?
the thing with the world is that you're the only person living in it. yeah. you are the only person that exists. everyone else around you is just you reflected back to yourself, like a pool. 
when you think the world is shit, the world is shit. you are the world. when someone else manifests something, they're not actually manifesting anything, because they don't exist.
this means, that if someone else manifested world peace, you wouldn't see the difference in your reality, because only your reality exists.
you have to do it yourself to see change.
so instead of jumping to conclusions and declaring things, you should try it for yourself! affirming that manifestation isn't real because someone else isn't manifesting something for you is a manifestation in itself. it's full circle.
