“The word is so powerful that one word can change a life or destroy the lives of millions of people.” Don Miguel Ruiz, author of The Four Agreements, writes about how influential our words can be. They are one of the most powerful tools we have. If one uses them maliciously or carelessly, manipulation and deception becomes very easy. Great speakers have always been the most powerful leaders. An example of this would be the play, The Tragedy of Julius Caesar by William Shakespeare. The main characters in this play are able to control people’s emotions and actions with a simple speech. In this play Shakespeare proves that language can be just as powerful a weapon as a sword.
