Step One: Even though no one is listening, say something. It will at least confirm that you are a humble person, and you might just hear yourself and come to life.
Step Two: If only one person is listening, say something. Or you could just sit idly whilst life passes stealthily and you remain anonymous, or worse, you have your listening population go back down to ONE..and by that I mean you go back to step one and become your audience.
Step Three: If you are still with me at this point, and you have an audience of two or more, say something. You are beginning to become relevant.
The bottom line is that there are words stored as impulses inside your head. They may not make everyone's day, but when you look in the mirror you will know that someone heard you, even if only you.
