It’s likely that you experience a variety of negative emotions every day — from waking up on the wrong side of the bed, to feeling frustrated during your commute, to being bothered by the pile of emails that awaits you at work. But you probably don’t express all those emotions once you get to work. After all, there are implicit norms for treating those around you with respect and courtesy, and you don’t want to create the impression that you’re constantly frustrated or irritated with them. You may also have heard about the benefits of maintaining a more optimistic outlook.
