Failure, or non-success, occurs when an individual or group does not achieve their intended goals or outcomes. It can happen in various contexts, such as academics, business, or personal endeavors. Failure is often viewed negatively, but it can also provide valuable lessons and insights for future attempts. In many cases, failure is a natural part of the learning process. For example, Thomas Edison famously failed thousands of times before successfully inventing the light bulb. These experiences can help individuals develop resilience and improve their strategies, ultimately leading to greater success in the long run.
