Words carry so much power, not just in their meaning but also in how they are spoken. For example i could pay a compliment to a man by saying "nice tie." He may take that as a compliment, an insult or a joke depending on my tone of voice. As a hypnotist I sometimes work from scripts (when my clients are hypnotized). I always edit the script before I read it to my clients, removing any words with negative associations like 'anxiety' or 'stress'. In the past those words carried such a bad connotation with my clients, so why would I want to expose them to the feelings that they evoke, especially in hypnosis? It is words that our entire system of government is based on. We communicate and learn by reading, writing and speaking words. Words, and how they are said, are so, so important in our lives.
