Growth mindset? Think of it as the key to resilience and success.
People and teams with a growth mindset believe that success is the result of effort. They believe that setbacks are learning opportunities.
(People and teams with a fixed mindset believe that setbacks are a sign that they don't have the intelligence or talent to succeed - and there's nothing they can do about it.)
To develop a growth mindset in your team (or children) praise effort, perseverence and resilience - never intelligence or talent.
