Guy wastes a lot of words to give some simple advice: SMILE.

If you want to make a good first impression, smile at people. What does it cost to smile? Nothing. What does it cost not to smile? Everything, if not smiling prevents you from enchanting people. If you don’t believe that smiling is useful, answer these questions:

• Do you like to do business with grumpy people?
• Do you know anyone who does?
• Do you think that angry people get what they want?

The key to a great, George-Clooney-esque smile is to think pleasant thoughts. If you’re grumpy inside, it’s hard to have a smile that lights up a room, and the most you’ll accomplish is a “fake smile.”

Also, this is uncharacteristically dark of Guy:

• We all die equal. At the end of your life, you’re going to be a mass of tissue and bone that reduces to a pile of dust like everyone else, so get over yourself. Death is the great equalizer.

I didn't think of it as dark, actually. It's humbling to remind ourselves of the fact that we are all equal in the end...so we should look at others with a healthy perspective.

In the words of Kansas, all we are is dust in the wind. Bill and Ted added "dude" to it:

Man, Keanu, what is UP with that hair?
