The "All or Nothing" concept refers to a mindset where individuals see situations in black-and-white terms, believing that anything less than complete success is a failure. This perspective can lead to unrealistic expectations and increased stress, as it does not allow for partial achievements or progress. In psychology, this thinking pattern is often associated with cognitive distortions, which can affect mental health. It can be seen in various contexts, such as sports, academics, or personal goals, where individuals may feel compelled to achieve perfection or nothing at all, potentially hindering their overall performance and well-being.
