I improved the content by removing much of the nominalization. I also chose to make some of the passages more succinct by removing the wordiness and repetition. I changed a few instances of passive voice to active voice. The passive voice isn't necessary when the sentence already has a subject ("you," in most cases).
For example, this sentence: "Every word must be carefully selected for inclusion in your speech." can easily be shortened and turned active: "Carefully select each word to include in your speech." I removed the nominalization of "select" and "include" while writing the sentence in an active voice.
