Words are tokens of ideas. We often soften hard truths or deceive through carefully chosen words that misrepresent the truth like a magician uses slight of hand. Some common things most of us have done are things such as -
1. "I can't..." When we say we can't do something what we are often really saying is "I don't want to." However, by using the word "can't" we are making it appear (to ourselves and others) that the situation is out of control. The next time you find yourself confronted with such a statement ask "Is it truly impossible for such a thing or are you just unwilling to do it?"
2. "I need.." or "My needs..." Air, water, food, and protection from the elements in the form of clothing or shelter are the only things we need. Everything else is a want or desire.
3. "?" End any sentence with a question mark and you can remove liability of liable or slander. People make accusations in the form of a question and then defend themselves with the statement "I was only asking a question. I didn't make any claims." However, when we hear a question we naturally draw a conclusion because the human brain hates mysteries.
We also excuse behavior by the way we describe things - "We are not at war. We are simply using our military to conduct a peacekeeping action in a foreign nation." "These are undocumented immigrants."
