“The brave man is not the one who has no fear, he is the one who triumphs over his fear.”

— Nelson Mandela

My friend Kamal is a world traveler. He has meditated with Tibetan monks in the Dalai Lama’s monastery, trekked the Himalayas, and hiked the Camino Real in Spain. He served in the U.S. Army and studied to be an ER doctor. He has launched tech companies, runs his own venture capital firm, and is a bestselling author. Up close, he makes quite the striking impression with his flowing mane of silver hair, quiet voice behind a steely gaze, and the super-calm demeanor of a Buddhist master. Here is a guy with all the ingredients for success on a mega scale. But I recently learned a secret about Kamal.

He couldn’t swim.
