@TG, I did the free science of well being class! I am not sure I learned anything new but it was nice to have all the information consolidated in one place. The articles and links are excellent but take a long time to read. The trait profile is fun.....I had DH answer the questions also.
I haven’t paid for online courses from Masterclass. DH and I once ordered a “Great Course” on CD to learn about Opera. It was well worth the cost and our time and energy to watch and learn.
