Influence and power are concepts that describe the ability to affect others' thoughts, behaviors, or decisions. Influence often comes from personal qualities, such as charisma or expertise, allowing individuals to sway opinions without formal authority. For example, a teacher can influence students through engaging lessons and mentorship. Power, on the other hand, typically involves a formal position or control over resources. It can be seen in structures like government or corporate hierarchies, where individuals or groups have the authority to make decisions that impact others. Both influence and power play significant roles in social dynamics and relationships.
