Write a paragraph that explains at least three characteristics of a proper summary. Include the words "mediocrity" and "ancient" in this response. Then, discuss something that should NOT be included in a summary.

A proper summary should be concise, objective, and coherent, capturing the essence of the original text without descending into mediocrity. It distills the main ideas and themes into a clear and succinct form, allowing the reader to grasp the fundamental points without wading through extraneous details. Just as ancient scholars would strive to render complex ideas into digestible forms, a good summary simplifies while preserving the core message. Additionally, personal opinions, interpretations, or extraneous information should not be included in a summary, as these elements can distort the author's original intent and mislead the reader. A summary’s role is to present the source material faithfully, allowing for clear comprehension without the influence of subjective views.
