I didn't write about the gratitude paper but I did enjoy reading it. Furthermore, it does in my opinion lend itself to the content of the video, in that when we are intentional about expressing gratitude it creates a positive thought, energy and vibration. In addition what I've learned about often expressing gratitude causes intentions to manifest more quickly. Essentially giving thanks for what you have but also giving thanks for what you've yet to obtain will bring those unseen things into fruition. I don't see it as any different than focusing on a positive feeling with respect to bio-hacking one's own attitude.
