As I’ve written about before, “happiness” is a terrible word to me. It’s my version of a four-letter word in regard to positive psychology and personal productivity. And yet, we continue to keep using it; I’m guilty of it as well from time to time. While it seems like a universal term, it’s actually a rather confusing word. If the purpose of communication is to convey information clearly to another, why circumvent the process with vagaries? Dr. Daniel Kahneman, who I’ve written about before, agrees with me in his famous TED talk, “Riddle of Remembering and Experiencing Self.” What does it mean when you say you’re happy? And, to what degree? Difficult to interpret, right?
