In this overscheduled, overstimulating world, it’s no surprise that many of us feel like introverts at some point during our days. In an excerpt from The TED Interview podcast, writer Susan Cain talks about how workplaces can better support people’s quieter side and what helped her conquer her fear of public speaking.

In her blockbuster TED Talk, Susan Cain has a call to action: Take introverts seriously, and understand what they can do in the right environment. Ben Lillie called her up for an extended conversation about the terrors of public speaking, how her issue is one of civil rights, and the neuroscience behind personalities.
