A while back I read a book called, Positivity: Groundbreaking Research Reveals How to Embrace the Hidden Strength of Positive Emotions, Overcome Negativity, and Thrive by Barbara Fredrickson. I liked the book. It explains about a new psychology called positivity.
But this guy explains it here so much better. He describes how happiness relates to greater performance, productivity, health, energy, and success rates. Happiness is a pre-cursor to success, rather than merely the result. Tasks performed when happy are performed at a higher level.
I know this is a lot of video, but if you are interested in greater creativity, you might be as fascinated by this stuff as I am!
Let me know what you think about these ideas. Thanks, Diana
