In boardrooms and on basketball courts, billionaire Mark Cuban says he's noticed one factor that consistently leads to success: team culture.

On an episode of the "Re:Thinking with Adam Grant" podcast this week, the "Shark Tank" investor and Dallas Mavericks owner said creating collaborative working environments is more important than amassing raw talent. He said he's fired business partners and traded basketball players because of their personalities — especially when the team has multiple self-centered or combative members.
