Mark Cuban has gone from selling garbage bags door-to-door to selling internet companies for billions, acquiring an NBA team, and becoming a beloved “Shark” on Shark Tank. Mark reveals to Adam how he turns problems into opportunities in entrepreneurship, basketball, and investing. They discuss his latest venture–disrupting the healthcare industry with an online pharmacy and a price-slashing philosophy that makes hundreds of drugs affordable–and why following your passion is not the best way to maintain your motivation.
