I’ve always been a list maker. I attribute much of my professional success and personal happiness to jotting down to-dos. Psychologists term this technique “compartmentalization,” and anytime you feel overwhelmed by life’s responsibilities is an excellent time to try it.

Psychologists define compartmentalization as a defense mechanism to avoid the anxiety that arises from the clash of contradictory values or emotions. While that may sound like a bad thing at first glance, it’s how our brains handle conflicting internal standpoints. For example, a manager can consider herself a relaxed mother or partner at home but a demanding boss at work. These two self-images can coincide because the manager compartmentalizes her life.
