Tell the audience what you will tell them, then tell them, and finally tell them what you told them. When pitching an idea, introduce yourself and what you are pitching for. Summarize your idea in one sentence explaining what you intend to make and why it will work for the intended audience. Then explain the details of the content, how it is practical given constraints, how it will appeal to the target audience, and how it is original yet recognizable to the audience while summarizing the best aspects of the idea.
