Back in my corporate days, I wasn’t always good at hiding my disappointment or dissatisfaction. It’s awful to think back on it, but I just couldn’t seem to help myself. I lacked the ability to properly manage my emotions. I didn't have self-management strategies.
The ability to self-manage is a component of emotional intelligence. Think of the leader who loses his temper with colleagues, or appears to lack integrity or ethics, the one who doesn’t take responsibility when things don’t go well, and the person who shows up unprepared for meetings. Or even the one who wears their emotions all over their face.
