About Susan Cain

The youngest of three children, Susan Horowitz Cain, was born in 1968 and raised in Lawrence, New York.[2] Her father was a medical school professor,and her grandfather was a rabbi from Eastern Europe who immigrated to the United States in 1927.[3] Though he intended to bring his family to the U.S. later, he could not come up with the money for it before the start of World War 2. As a result, much of Cain’s extended family on her father’s side did not survive the Holocaust.[4]

Cain’s mother practiced Orthodox Judaism, though Cain herself pushed back on many restrictions of the religion. She says this is likely due to the mixed influences she received, as her father was not religious.[4]

As a child, Cain aspired to be a writer. In fifth grade, she began writing plays and magazines. She says she has had an introverted personality her whole life. She states, “I’ve been aware of it since I was 4, even though I didn’t have a language for it.”[2] 

She describes her hobbies, saying, “I prefer listening to talking, reading to socializing, and cozy chats to group settings.”[5] 

Education and Professional Life

Cain earned a bachelor’s degree in English from Princeton University before earning her law degree at Harvard Law School in 1993.[6] After law school, she spent seven years working for the law firm Cleary Gottlieb Steen & Hamilton.[7] She then left to start her own consulting firm, which she ran for four years. 

In 2012, Cain published her first book, Quiet: The Power of Introverts in a World That Can’t Stop Talking. The book landed on numerous bestseller lists and launched Cain to fame. It remained on the New York Times best seller list for sixteen weeks.[8] Based on the book’s themes, Cain’s Ted Talk, “The Power of Introverts,” reached one million views faster than any other Ted video. As of 2023, it has over 32 million views.[1]

After the success of her first book, Cain published Quiet Power, which discusses introversion in kids. She also released the Quiet Journal and the Quiet at Work Course. In 2015, she founded Quiet Revolution, a company that trains introverted leaders, supports introverted children, and works to rebalance the power between introverts and extroverts. 

Susan Cain’s latest book, Bittersweet: How Sorrow and Longing Make Us Whole, was released in 2022. It debuted at number one on the New York Times best seller list and was chosen as part of Oprah’s book club.[9] Oprah stated, “This book has the power to transform the way you see your life and even the world. I have started to look at my own life in the world differently.”[10]

Cain has written for several publications, including, The New York Times, The Atlantic, The Economist, TIME, and The Wall Street Journal.[11] She has spoken at Google, PIXAR, the U.S. Treasury, P&G, Harvard, and West Point.[12] She also curates the Next Big Ideas Book Club with Adam Grant and Malcolm Gladwell.[13]

  • “Spend your free time the way you like, not the way you think you’re supposed to.”[20]
  • “There’s zero correlation between being the best talker and having the best ideas.”[20]
  • “We don’t need giant personalities to transform companies. We need leaders who build not their own egos but the institutions they run.”[20]

  • “If we could honor sadness a little more, maybe we could see it—rather than enforced smiles and righteous outrage—as the bridge we need to connect with each other. We could remember that no matter how distasteful we might find someone’s opinions, no matter how radiant, or fierce, someone may appear, they have suffered, or they will.”[4]
  • “Whatever pain you can’t get rid of, make it your creative offering.”[4]

Personal Life

Cain met her husband, Ken, after leaving her job at a law firm. He was a writer who worked doing peacekeeping negotiations for the U.N. He encouraged her to pursue her writing career. Cain and her husband now have two children together, Eli and Sam.[4]
