“I realize it’s not true that I’m no longer shy; I’ve just learned to talk myself down from the ledge (thank you, prefrontal cortex!). By now I do it so automatically that I’m hardly aware it’s happening. When I talk with a stranger or a group of people, my smile is bright and my manner direct, but there’s a split second that feels like I’m stepping onto a high wire. By now I’ve had so many thousands of social experiences that I’ve learned that the high wire is a figment of my imagination, or that I won’t die if I fall. I reassure myself so instantaneously that I’m barely aware I’m doing it. But the reassurance process is still happening— and occasionally it doesn’t work.”
