I'll be honest with you -- for me, it had been months. As a recovering workaholic and someone who is fairly obsessive about productivity and effectiveness, I always struggled with the idea of play. 'Play' felt a little like a four letter word.
Why? Because, at the end of the day, what does dancing around my office singing Katy Perry at the top of my lungs actually produce? Sure, it burns a few calories and relieves writer's block, but isn't that time that I could be using more productively, more effectively?
