Almost everything we do involves words.

"Words," says Wharton professor Jonah Berger, "are how we persuade, communicate, and connect. They're how executives lead, salespeople sell, and parents parent. Even our private thoughts depend on language."

But while we live in a world awash in words, we're strangely indifferent about which ones we use. We focus on the ideas we want to convey, not the best way to articulate them. And that, according to Jonah, is a big mistake because "subtle shifts in the words we use can have a big effect on our impact."

This week on the show, he'll teach you how to make those subtle shifts so you can become a better communicator, a better persuader, a better friend, and a more confident, effective person.

Jonah's new book is called "Magic Words: What to Say to Get Your Way."
