Amazon founder and CEO Jeff Bezos is a lot more hands-on than you might expect.

Though he oversees the direction of a $433 billion enterprise, he pays very close attention to the inner workings of the company, according to Brad Stone's unofficial biography, "The Everything Store: Jeff Bezos and the Age of Amazon" and multiple reports citing company insiders.

Since he makes so many decisions each day, both big picture and detail-oriented, Bezos developed a phrase he says helps him navigate his business more quickly.

It's "disagree and commit," and Bezos says every professional should start using it.

"This phrase will save a lot of time," Bezos writes in Amazon's 2017 annual shareholder letter.
