Those with a fixed mindset believe intelligence is innate and unchangeable, leading them to focus on performance goals where success or failure validates their ability. They see effort as a sign of low intelligence and give up easily. In contrast, those with a growth mindset see intelligence as something that can be developed through effort and learning. They focus on learning goals and mastery, seeing effort as key to success. When faced with challenges, those with a growth mindset try new strategies rather than giving up, believing their abilities can be improved through hard work.
