Yale University is offering a FREE (yes free) online class about the Science of Wellbeing.
I was immediately skeptical but upon further research have concluded:
1) It's real and will be informative and
2) I'm obsessed with online tests.
I've signed up for the course and have taken the "rewirement" assessments (also all free) that have included a baseline Happiness Assessment, Positive Emotion, Engagement, Relationships, Meaning, and Accomplishment (or PERMA™) Assessment, and a Character Strengths Profile Assessment (with recommendations on things to try this week to see if it increases my happiness).
Details on the course are in the article and a direct link to the Coursera class can be found here: https://www.coursera.org/learn/the-science-of-well-being/home/welcome
