Here’s another article for those of you that like brain research like I do: "Effects of gratitude meditation on neural network functional connectivity and brain-heart coupling." Practicing gratitude meditation on a regular basis makes you feel better. When you feel better, you have the energy and motivation to do more. When you get more done, you feel accomplished and grateful. The connection strengthens and then you feel even better. This isn’t just woo-woo good ju-ju stuff. This article provides a scientific study (with graphs and cool brain scans!) to prove it:
"Furthermore, our findings shed light on the power of gratitude intervention on mental well-being as a means of improving not only emotion regulation, but also self-motivation, by modulating rsFC in emotion- and motivation-related brain regions."
