Reacting in anger or annoyance will not advance one's ability to persuade.

Summary

This quote emphasizes that responding with anger or annoyance when trying to convince or persuade someone is unproductive. It suggests that expressing hostility or irritation only serves to hinder one's ability to effectively communicate and persuade others. Instead, maintaining a calm and composed demeanor is more likely to facilitate constructive dialogue, promote understanding, and increase the chances of successfully persuading one's audience.
