Leaving Comfort Zones Dear HBR:

How do you feel when you have to do something new or difficult? Dan and Alison answer your questions with the help of Andy Molinsky, a professor at Brandeis International Business School and the author of "Reach". They talk through what to do when you’re terrified of giving presentations, big changes at work make you uneasy about the future, or your voice quakes when you deal with conflict.
