Im not here to make you believe in manifestation. Nobody is and those who know it works through their life experiences, know.
I see why you would think these things and while in many opinions we clash, let me say this:
You don’t need manifestation to make subs work. It’s an addition for those who wish to use it. I would argue that it can give you infinitely better flow if you do it right.
If you don’t wish to manifest, that’s fine. It’s not everyone’s cup of tea.
