Actually, people tend to prefer the more energetic opposite sex. Because if a person is full of energy, enthusiasm, curiosity, and initiative, it naturally makes others feel happy, inspired, and more willing to get close to you, cooperate with you, or build relationships. Conversely, people who are consistently negative, complain, or lack vitality will unconsciously drain others' emotions and attention. Therefore, improving one's mental state, physical condition, and passion for life is itself a form of attractiveness, rather than relying on deliberate flattery.
