Speaking skills can be divided into categories including posture, body language, and grammar. Developing public speaking skills often begins with classes in school that teach skills like structuring a speech with a clear introduction, body, and conclusion. Speaking skills provide advantages like the ability to inform and persuade audiences as well as enhance one's career. Public speaking is feared by many but can be improved by thoroughly preparing for speeches, making eye contact with the audience, and avoiding distracting mannerisms.
