Brené Brown recently published Atlas of the Heart, a compendium of 87 key human emotions. Chapter 11 entitled Places We Go When Life Is Good, delves into a multitude of emotions, including joy, happiness, calm, contentment, and gratitude.

Besides being a best-selling author, Brené is a successful podcaster, professor, and lecturer. She is best known for her extensive research on shame, vulnerability, fear, and leadership, and she has an incredibly popular 2010 TED Talk on vulnerability. Her Netflix special, A Call to Courage, is also powerfully insightful. Both are worth watching.

Here’s what she has to say about gratitude in Atlas of the Heart:

“There is overwhelming evidence that gratitude is good for us physically, emotionally, and mentally. There’s research that shows that gratitude is correlated with better sleep, increased creativity, decreased entitlement, decreased hostility and aggression, increased decision-making skills, decreased blood pressure–the list goes on.”
