I’ve had the good fortune to meet Paul McCartney a few times. And I say “good fortune” not just because it’s cool meeting famous people; I say “good fortune” because of the lesson I learned—and re-learned—from this guy (who, as a refresher to our younger readers, was one of the Beatles).

Think about this: Paul McCartney is arguably the most famous person of the last 50 years. Sure, in any given year there may be people who are more famous, but if you take the past 50 years in aggregate, McCartney is certainly up there. And he’s not just famous for being famous; he’s famous for continually producing high level work (with a few exceptions, of course) that brings pleasure to millions. The point is that if there’s anybody who could feasibly be justified in having a haughty, condescending, or “better than you” attitude, it would be Paul McCartney. But here’s the thing:

Every time I’ve met him, he’s gone out of his way to make me feel like I’m the most important person in the room.

And this is not because of some magical bond I have with McCartney. I know dozens of people who have met and/or worked with him, and judging from their stories, he treats everybody the same way.

Now, having written that, I’m sure I’ll hear from somebody who’s had a different experience. We all have our off days. (Jay Leno once told me that if he accidentally snubs, say, the 637th person out of 1,000 that he meets in a week, he’s that person’s “Jay Leno is a jerk” story for the rest of their life—a story that they’ll share with their friends, family, co-workers, and anybody else who will listen.) So yes, I’m sure that Paul McCartney has his equivalent of that 637th person. But it’s never been me. And from what I can tell, it’s the exception.

So my question to you is this: If a guy like Paul McCartney can treat others as if they are the most important person in the room, what about you? How might your business, your sales conversions, and your personal relationships change if you truly made a conscious effort to treat the person you’re with (either in person or on the phone) as if they were the most important person in the room?

Why not take the next month and find out?
