Life changes can sneak up on all of us, and sometimes they hit pretty hard. Cassidy Krug spent 20 years training to be one of the best divers in the world. She made it to the Olympics. And then, in a single moment, her lifelong dream ended—with no medal, no encore, just the quiet shock of “What now?” Cassidy’s new book, Resurface, is a guide for anyone navigating life’s big transitions—grief, identity shifts, career changes, reinventions. In the book, she gathers wisdom from Olympians, veterans, new parents, and more. Below, she shares what she’s learned about letting go, asking for help, and redefining success.
