I have never been the same since. The part of me that was wounded was healed. Many things like that have happened on the stage. Promoting my show has developed a whole other part of me. The fearlessness, facing rejection time after time until it doesn't matter is a path.
Writing is another place to do that.
That's what you will gain through writing. And I meet with people privately to help organize them. Usually they will have an idea of what it is they need to write. It is usually based on some need of their mothers or some need for attention. Something they didn't get they hope writing will gain them, not the writing itself.
