Can Your Beliefs Actually Change How You Age? | Shawn Achor

5 min read

Shawn Achor, the Harvard-trained positive psychology researcher behind The Happiness Advantage and Big Potential, spent years as the youngest person in every room. Then he turned 40, his daughter Zoe was born prematurely and spent 50 days in the NICU, and he made the decision to become a stay-at-home dad for eight years. Watching peers take over the space he had occupied, he felt replaced. At a Target talk, he got two news alerts in one morning: a contemporary had a number one bestseller, and someone else landed a project he wanted. He spiraled into feeling he no longer mattered. Then a stranger shook his hand on an escalator and said, "I read your book and it saved my life." Achor calls this the constant tug of war between wanting what you don't have and not wanting what you do. His new book, The Power of Beliefs, is his attempt to understand how the stories we tell ourselves — about aging, about our value, about whether our behavior matters — actually shape our outcomes.
