Keep in mind that you have already processed your information. You are speaking because you probably know more about the topic than your audience. Avoid the temptation to dump everything you know so fast that people feel overwhelmed. Your audience may be hearing your information for the first time. They will welcome a little extra time to digest it.
Allow three seconds of silence after making an important point or when asking a question, even if the question is intended to be rhetorical. Good attention management includes knowing when to place the attention on your audience. Allow people some time to reflect on what your information means to them.
