How I Built This celebrates 10 years of 600+ founder interviews by replaying pivotal moments—from lightbulb ideas sparked by moldy fruit to founders nearly giving up. Guy Raz and Ring founder Jamie Siminoff explore why fear drives entrepreneurship, how luck and skill combine on the path to success, and why failure isn't failure at all—it's iteration. Founders distinguish between scary (like quitting your job) and dangerous (like staying in a comfortable path that wastes decades), and recognizing the difference unlocks risk-taking.
