Active Listening?

In Leadership Gold, John Maxwell writes...

"I once read about a study that stated that we hear half of what is being said, listen to half of what we hear, understand half of it, believe half of that, and remember only half of that. If you translate those assumptions into an eight-hour day, here is what it would mean:
- You spend half your day - about four hours - in listening activities.
- You hear about two hours' worth of what is said.
- You actually listen to an hour of it.
- You understand only thirty minutes of that hour.
- You believe only fifteen minutes' worth.
- And you remember less than eight minutes of all that is said."

Should we talk in 8 minute intervals? :-)
