In "Resistance to Civil Government," Henry David Thoreau uses ethos in order to help his audience gain trust in him. Thoreau uses his own personal experience in order to demonstrate his knowledge of his topic and his own personal connection to it. By using ethos in this rhetorical situation, Thoreau is attempting to inspire trust in his readers and establish his own credibility.
My best guess for this question is to find good topic to talk about, and if your topic is too broad it may be hard to find information. So if your topic is too broad you have to do a lot of research, and find information that you thought made sense.
