summary
In this chapter, Zinsser stresses the importance of keeping and developing your voice. By keeping one voice, the author means that writers should develop their own styles instead of changing their voices according to the subject. Developing one voice needs writers to give enjoyment to readers both in cadences and words and avoid problems like breeziness, condescension and clichés. In fact, how to create enjoyment for readers relies on the taste. Although it changes through time, there are timeless truth surviving in the end. Therefore, writers should choose words that have surprise, strength and precision and sentences that fit the article perfectly.
