I personally have been using a gratitude protocol for the last several years. But that protocol was based on my ignorance, really, about the scientific literature, and was mainly based on what I'd heard out there in the internet, which is that I should list out or think about, or verbally recite the things that I'm grateful for. The sort of protocol that we arrived at today based on the scientific literature is distinctly different from that.
