If your self-efficacy is high, you are more likely to think that a goal is realistic.

Self-efficacy refers to an individual's belief in their ability to successfully execute a specific task or achieve a certain outcome. When an individual's self-efficacy is high, they are more likely to believe that they can attain their goals, and therefore are more likely to perceive their goals as realistic. This suggests that high self-efficacy can positively impact an individual's level of motivation and determination to attain their goals.
