I try when I'm writing to leave enough "space" for people to have their own interpretation, and not to direct it toward one conclusion. Then the audience would not be reacting, because they are being preached to or lectured at. I don't have that much to say that I think people should listen to me.
The words "I Can't" should be permanently stricken from your vocabulary, especially the vocabulary of your thoughts. You must see yourself always growing and improving.
