If you think you are invisible (some do) and you have no voice (some people have this experience) then once you are aware of this fact you want to change it. How do you become visible to those who apparently can’t see you? How do you find your voice when you have people around you that won’t listen to what you have to say?
You take the first step for yourself which is to stop. Check in and see if you can notice how you are showing up and how you are speaking.
The second step is to listen to what you are saying and how you are saying it. If you are adapted, for example to speak so the other person won’t get hurt or mad at you, chances are your voice is not coming from a place of power.
Third, become aware of the choices you are making when you are speaking to those who can’t see you or hear you.
You have a powerful spirit within you that wants to be seen and hear. It just needs your conscious commitment to activate it.
