Having a voice is much more that being able to speak. A voice doesn’t refer to a sound, but a mind, a viewpoint, a consciousness that views, interprets and defines and evokes. It is the greatest gift that is wasted when it is not used. Never let anything prevent you from using your voice, even when everything seems to prevent it.
