People tend to use careless language when they speak because they assume other people know what they mean. Unfortunately, they often leave others uncertain or confused about what they want.
At the New York Center for Critical Thinking, they recommend that you pay close attention to the way you express yourself. Think before you speak, and make sure to present your thoughts logically. It helps to use examples.
