Setting realistic goals is important because they provide clear direction, focus, and motivation, which increase the chances of success. Realistic goals help break down aspirations into manageable steps, fostering resilience, adaptability, and continuous improvement. Achieving realistic goals builds confidence and improves self-esteem as each success releases dopamine, the "happy hormone," boosting mood and motivation. Unrealistic goals often lead to frustration, demotivation, and a negative self-image, whereas realistic goals encourage sustained progress, better time management, and strategic planning by aligning with an individual's skills, resources, and timeframe. They also help maintain motivation by setting achievable expectations, thus reducing disappointment and promoting a positive mental attitude toward goal pursuit.
