Cool and Good aren’t the same thing.

Some of the best people I’ve ever met were pretty low key and definitelly weren’t overly concerned with presenting an appealing image to others.

What’s percieved as coolness usually is just dressing the part and acting the part and in my experience “cool people” are often people who just take the whole maintaining a public persona thing to quite extreme levels, pretty much playing a role as if life was a Theatre play.
