Flow is a mental state where a person is fully immersed in an activity, experiencing a sense of energy and focus. This state often occurs when individuals engage in tasks that challenge their skills but are still manageable. During flow, people may lose track of time and feel a deep sense of enjoyment and fulfillment, which can enhance creativity and productivity. The concept of flow was popularized by psychologist Mihaly Csikszentmihalyi, who identified key elements that contribute to this experience. These elements include clear goals, immediate feedback, and a balance between challenge and skill level. Achieving flow can lead to improved performance and overall well-being.
