I have a voice and was always considered "stubborn" or the "black sheep of the family" because of my bullheadedness....I was the "bad child" - defiant, etc.
Yet, these traits have helped me through some really difficult situations in support of the same people who called me "bad"! I guess it was just the way I channeled it back then versus how I use it for good instead of evil now...LOL....

I seemed to have lost my voice for a while there - suffocated by my husband and some friends....But I've found my voice....And they're not liking it....But my T is!
