Some emotions make productivity plummet. If you feel sad, grieving, depressed, or ticked-off, the best way to feel better is to help another person. Do a secret kind act for someone TODAY. If s/he finds out, pick someone else to help. Be especially kind to that coworker who annoys you. Pay for the lunch of the stranger in the car behind you at the drive-through. When you focus on helping others, you end up helping yourself. And when your mood improves, so does your productivity.
