When building a first impression, the role of language should not be underestimated. Using a positive tone and clear expression can capture the other's attention instantly. Picking apt topics, along with humor and empathetic language, can swiftly lessen the emotional distance with others. Remember, communication is not only about speaking, but listening is crucial too. Through active listening, you can comprehend the other person's needs and thus respond more precisely, creating a favorable interactive ambiance.
