If you want to be wise, learn how to ask wise questions.

Proverbs 20:5 says, “People’s thoughts can be like a deep well, but someone with understanding can find the wisdom there” (NCV). In other words, everybody has something to teach you. You may have to draw their wisdom out like water from a deep well—but it’s worth the time to do that.

How do you draw the wisdom out? You learn to ask smart questions.

As I’ve traveled around the world, I’ve asked questions of taxicab drivers and prime ministers—and they all have taught me something. If you know the right questions to ask, you can learn from anybody!

One thing I’ve realized is that I never learn anything while I’m talking. If my mouth is moving, I’m not learning. You don’t learn when you’re talking either; you learn when you’re listening. So you’ve got to learn to listen.

The late American TV host Larry King once said this: In an interview show, if the host is talking 50 percent of the time, something is terribly wrong. The host should listen the most and talk the least. A good TV host sets up the question and then just listens.

I’ve done a lot of interviews over the years, and I’ve noticed fewer and fewer hosts following Larry King’s advice. More often, interview shows are about the interviewer—whose goal is to draw attention to themselves—and not about the guests.

In your life, be more like the host who has learned to listen. Be a person who believes you can learn from anyone.

You just have to be willing to ask good questions—and then listen. That’s the mark of a wise person.
