Words backed up with emotions are so much more powerful

"What is it that makes language powerful? I can give you a simple answer: words filled with emotion.
Words themselves are powerful, but not nearly as powerful as those loaded with human emotion. Hate, love, anger, contempt, caring and compassion are all part of the full spectrum of human emotion available to all of us. Emotion is what makes language powerful enough to accomplish the task, move somebody to action, correct a problem or find a solution. Here's where intensity plays its part: It changes the power of the word. Picture a word as a little straight pin. If I have a little straight pin and I threw it at you and hit you on the hand, you'd feel it. I've touched you with my words. But what if I took that little straight pin and wired it to the end of an iron bar? I could drive that pin through your heart. The pin is the word, and the iron bar is the emotion. Words backed up with emotions are so much more powerful. The emotions change the effectiveness of the word."
Keep in mind, however, that emotions must be well-measured."
