Which of the following is a common mistake made when setting goals?

Focusing on perfection can lead to setting unrealistic expectations, which makes it a common mistake when setting goals. This approach often results in discouragement and frustration. Instead of encouraging progress, the pursuit of perfection can cause individuals to become overly critical of their efforts and may even lead to procrastination, as they may fear that their performance will never meet their high standards.

Successful goal-setting should prioritize flexibility, progress, and personal growth rather than an unattainable ideal. It's more effective to set goals that allow for mistakes and learning along the way. This mindset can foster resilience and motivation, as individuals learn to celebrate achievements, even if they aren't perfect. Therefore, while the other options highlight important aspects of effective goal-setting, such as measurability, clarity, and attainability, focusing on perfection can hinder the actual process of reaching those goals.
