The Happiness Lab
Savoring and novelty are two things I mentioned in previous posts that contribute to happiness. If you would like to explore this topic more, I recommend The Happiness Lab podcast.
Dr Laurie Santos and her guests take you through the science, research, and experience of happiness. The topics are wide-ranging, from ancient philosophers to our tendency to like to complain.
Find it online at https://www.happinesslab.fm/ or wherever you listen to podcasts.
You can also take a Coursera class led by Dr Santos called The Science of Well-being. My book club did it together and I enjoyed it. https://www.coursera.org/learn/the-science-of-well-being
