I tried Mark Cuban's morning routine for a week—and it boosted my productivity significantly

Mark Cuban fits a lot into each day: He stars on "Shark Tank," owns the Dallas Mavericks and is a father of three. The rest of Cuban's morning includes catching up on the news, working out — he prefers pick-up basketball — and drinking a cup of decaf coffee. "Every morning, I'm rising, I'm grinding, I'm learning," Cuban tells fellow "Shark Tank" star Daymond John.
