I completed this quest twice. And it helped me a lot with letting go of the how and surrender to my frequency of knowing. Knowing and trusting that I can manifest anything I desire.
I haven't manifested my short term manifestations, but the big long term manifestation happened before I expected, in really strange way, because I didn't need money for it, yet, but rather started living my desired life already in the place I wanted to live. Now, I am living to manifest the money part to complete my project.
Overall, I recommend this quest, not just to manifest anything, but to live in coherence with who you choose to be in the now.
