Growth mindset describes a way of viewing challenges and setbacks. People who have a growth mindset believe that even if they struggle with certain skills, their abilities aren’t set in stone. They think that with work, their skills can improve over time.
People with the opposite belief — that abilities are what they are and won’t change — have a fixed mindset. They think their skills won’t improve no matter how hard they try.
The mindsets aren’t set in stone. People may have a growth mindset at certain times and a fixed mindset at others. They may have different approaches to different challenges. And their mindset may change over time.
