In the art of lies, understanding oneself and having strong metacognition are fundamental principles. Lying is an art. There are no set formulas for it, so you have to create your own, as it's a skill without predetermined answers. This uniqueness makes it easy for some and very difficult for others. In essence, it's an area that requires excellent metacognition, making it easier for those who excel in it, while it remains elusive for those with limited metacognitive abilities. In the end, understanding oneself is crucial to grasp the surrounding circumstances, control one's attitude accordingly, and effectively utilize the art of lying. The absence of a set formula for the 'art of lying' is due to the fact that we all emit different vibes inherently. Our facial features, body postures, speech intonations, and unique behavioral habits all differ, so you must craft your own style. In short, knowing oneself allows you to skillfully employ lies according to your own style.
