Our words make the strongest impression when we are both confident and knowledgeable in what we are speaking about. When we are sure of ourselves, people will be more interested in what we have to say. The more we understand a topic, the better equipped we are to answer questions people ask and to address any arguments they might have. If you want to be compelling, you must incorporate study and exercises to boost your overall level of self-assurance. When you have the knowledge to back up your words, you have so much more to offer the world.
