My wife told me one day that I am calmer, less confrontational and more considerate lately with her and others and wondered what had changed. As I thought about it I realized that it has been since I began carrying. Carrying a lethal weapon is an immense responsibility and has caused me to be more aware and more prepared for other peoples actions and therefore I'm less startled and less reactive. Therefore, I don't buy into your stage 1, 2 or 3. As for the rest, once I made the decision to carry there was a concurrent commitment for continuous education and training.
