Take a Risk... Learn from those who were told they were "failures"
I found this video via another interesting Positive Psychology Site: Happify. Though Happify is not specific about Workplace Happiness, I'm learning that so much about Happiness is "universal." The lessons we learn about happiness apply whether we're at home or at work. Hopefully, you work at a place where it is OK to fail, as long as you learn from that failure. Failures help us grow!
