Tony Robbins has a packed resume: he's a bestselling author, entrepreneur, philanthropist and renowned motivational speaker. In addition to being a self-help titan, Robbins has advised presidents and star athletes, and is involved in 31 businesses which he says generate annual sales of $5 billion. He joins Katie and Brian to discuss his difficult childhood, his remarkable career, his new book, and how President Trump's leadership style compares to President Obama's. Plus, he explains why he jumps into a cold pool every morning and demonstrates some "radical explosive breathing" exercises.
