Finding your voice is a reflection of who you help.
Your voice is your story, your ideas, your experiences. They are told from the perspective of helping someone, of being of value.
It is in the communication of those thoughts and ideas that you find your voice.
Communication is what the other person hears not what you say. Finding your voice therefore means finding your audience and understanding your audience and learning how to communciation so that they hear what you are trying to say.
Finding your audience helps you refine your voice, finding your voice helps you find your audience,
Always focus on both.
