In my role as a professor at the Brandeis International Business School, I teach a course each fall about acting outside your comfort zone. Each student in the class chooses a behavior outside their comfort zone to work on. For some, it’s public speaking; for others, it’s networking, making small talk with strangers, or being assertive. Students have to go to actual networking events or give speeches in front of real audiences. After the fact, they compile a diary about their experiences, and we discuss and debrief as a class.
