As a young girl, Maya Shankar was well on her way to a promising career as a classical violinist. The famed Itzhak Perlman had taken her on as his private student at The Juilliard School at the age of 14, and she was accepted to his prestigious summer program on Shelter Island. But not long after, she injured her finger while playing a difficult section of Paganini’s Caprice no. 13. She tore a tendon in her hand, putting her musical career to an untimely end.

Today, Maya has reached a new pinnacle in an entirely different field. At the age of 30, she is a senior adviser at the White House, working to create better policy using insights from behavioral science. Her work in government is far-reaching — helping students get to college, workers save more for retirement and millions of children get access to school lunch.

It’s a new calling, and one she couldn’t have anticipated at Juilliard, where she dreamed of being a concert violinist. What followed in the days after her musical career ended was an incredible sense of loss.

“I was really devastated to lose something that I was completely in love with, and so passionate about, and that had really constituted such a large part of my life and my identity,” she says. “I was first and foremost a violinist.”

This week on Hidden Brain, we look at turning the page and starting anew. At the end of the podcast, you’ll hear musician Aimee Mann read a poem by Emily Bishop.

Special thanks to NPR’s From the Top with Christopher O’Riley for music of Maya’s performances used in the episode.
