I see introversion and extroversion in general as just two different kinds of strengths. The problem in our culture is just that we emphasize one type of strength, the extroverted strength, usually more than we do the introverted strength, but that they're equally valuable.

**Lenny Rachitsky** (0:13)
There's probably not this binary thing, you're introvert, extrovert, it's a spectrum of introvertedness, extrovertedness. Do people move along the spectrum often? I feel like I've definitely become more extroverted over time.

**Susan Cain** (0:23)
I've had the exact same trajectory you just described. I used to be terrified of public speaking, now I do it all the time, I used to be quite shy. But that's not really describing, I don't believe, becoming more extroverted. That's more describing acquiring skills. As we grow and gain experience, we acquire all kinds of skills.

**Lenny Rachitsky** (0:43)
What people most want is just like, how do I become potentially more extroverted slash less allow introvertedness to hurt me in my career?

**Susan Cain** (0:49)
This is a paradox that I have observed, that the more introverts become deeply comfortable in their own skin, that's when they start to show up at the job interview or on the stage in a more powerful way because you're now there as your own true being as opposed to there always being a voice in your head saying, I'm not really supposed to be me.

**Lenny Rachitsky** (1:11)
How can you help people believe this is actually true, that you can be just as successful being very true to yourself versus learning to be an extrovert?

**Susan Cain** (1:17)
One of the most important things you can do.

**Lenny Rachitsky** (1:23)
Today, my guest is Susan Cain. Susan is the author of the number one New York Times bestseller, Quiet, The Power of Introverts in a World That Can't Stop Talking. Her books have been translated into 40 languages, her TED Talks have been viewed over 50 million times, and she basically made me and every other introvert in the world feel okay about being an introvert, and showed that actually embracing that about yourself can unlock a ton of opportunity and success in your life. In our conversation, Susan shares a ton of very tangible advice for how to be more successful in business as an introvert, including what skills you should actually be building that don't come naturally to you, also what actually is an introvert, how to raise kids who might be introverted, and so much more. This was such a wonderful conversation, and so much of it resonated with me.
