The first guideline for generating original material is to begin. Experiment, make errors, put your hypothesis to the test, and learn from the outcomes. If you know a lot about a topic, you've probably acquired an intuition for detecting patterns in that discipline. As a result, if you are an expert in a certain area, you may confidently rely on your intuition when making judgments that are directly linked to your field of knowledge.
No matter how original your work is, certain concepts shared by your audience will not detract from it. Give your audience a hint that will help them comprehend and appreciate the uniqueness of your idea.
