Fixed mindset is the enemy of growth mindset. Fixed mindset is the belief that abilities and intelligence are fixed traits that cannot be changed, leading to a fear of failure and a reluctance to take on challenges. This mindset can hinder personal and professional growth as individuals may avoid trying new things or taking risks in order to protect their self-image. In contrast, growth mindset is the belief that abilities can be developed through effort and perseverance, leading to a willingness to learn from mistakes and embrace challenges as opportunities for growth.
