The problem with woo is you can always add more woo (bonus points if it has sciencey glitter). Goes from woowoo to woowoowoo.
Woo has no logical consistency and has nothing predictably predictive.
Ask manifestation believers why they are not successful or rich or whatever? You'll hear some fabulous reasons.
My neighbour paid money (I presume thousands) to do courses on learning how to unblock herself. The stated reason for the failure to manifest was due to blocks. Her explanation of the material was outrageous. I have yet to see the positive effect on her.
I don't manifest, yet I've got things others would like to manifest. Not sure there that fits in with the woo.
But after some time goes by and you get pinched in the mortgage crash, or your wife hits you with a divorce, or you get cancer, if you really believe you manifest everything into your life, then you have to believe you manifested the bad stuff too. So why did you do that to yourself? It's a rough belief system then.
Truly a master of manifesting my own reality, I suppose? heh. But seriously though, in think in the vain of the above, if "manifestation" is what someone needs to do as their trello or jira for themselves, more power to them.
