A "Persona" is a character or identity that someone adopts, often to connect with others or to express themselves in a specific way. This concept is commonly used in marketing, where businesses create buyer personas to understand their target audience better. By defining traits, preferences, and behaviors, companies can tailor their products and messages to meet the needs of their customers. In everyday life, people also have personas that reflect different aspects of their personality. For example, someone might have a professional persona at work, while showing a more relaxed persona with friends. These different identities help individuals navigate various social situations and relationships.
