Cain wishes she had known more about introversion when she was younger, and she advocates for self-awareness. She reflects on the young people she and her colleagues met while researching, including Ryan, whose essay she quotes, sharing his remark: “‘I now feel no qualms accommodating my introversion […] It isn’t a secret to be covered up or a blemish to hide. I don’t hold myself to the extrovert ideal anymore, and it is more freeing than I ever could have imagined’” (228). Cain references Peter, a smoker, who developed self-awareness, started accommodating his introversion, and was able to quit smoking.

Cain concludes with a few reminders, encouraging readers to embrace their introversion, expand their comfort zones, find and pursue their passions, take time to recharge, value time with friends, and consider befriending someone with different personality traits. She also pushes readers to believe in and speak up for themselves.

Cain reflects on a letter she received after publishing Quiet. The sender—a teacher named Mrs. French—wrote to say the book changed her perspective. She shared more about introversion with her students, and the students developed a research project examining introversion in their school.
