Arianna sits down with business mogul, Dallas Mavericks owner and "Shark Tank" star Mark Cuban for a funny, revealing far-ranging conversation. In typically outspoken fashion Mark shares his best (and worst) life hacks, his thoughts on Donald Trump, and regales us with tales of “reverse” mentors and how he uses his geek superpowers to keep tabs on his kids. They even explore why he recently donned a jersey with the number "46." The Thrive Global podcast is brought to you by Sleep Number.
