Holding a grudge is letting someone live rent free in your head.

Think about all the clothes in your closet. Think about your favorite shirt, pants, or shoes. Can you remember a time when someone complimented you while wearing them? Do you remember what was said? When it happened? How it felt?

Chances are, you remember these moments somewhat vividly.

Now just imagine... you have the power to make that deep of an impact every time you engage another human — online or in person. With a moment of thought and a well placed compliment, you can live rent free in someone's mind for years.

As they say in real estate, "Location. Location. Location."

Your mission, should you choose to accept it, is to identify someone whom you greatly admire and reach out to share your genuine appreciation in the most detailed and expressive manner possible.
