(I had to repost my review from 2007, because I still love the philosophy behind it.)
In this world, where nobody makes any mistakes, because he who makes them is a loser, where nobody has deficiencies, nobody is wrong - ever -, everybody is rich and good looking and intelligent and famous and a role model for the masses and the media, there are unfortunately millions who pretend to be like that and just a few who are really like that. The latter works and sweats a lot for that, the former thinks he has the talent to be like that, just like that.
Carol describes in her book that those two differ by mindset. The former has a so-called fixed mindset, meaning he is convinced, talent is a given and his qualities are carved in stone, the latter believes, her basic qualities are things she can cultivate through her efforts, and that everybody can change through application and experience, ie. she inhibits the growth mindset.
The fixed mindset is about making no mistakes at all, being perfect on the spot, dreaming of "effortless perfection".
For the growth-mindset it is not about immediate perfection. "It's about learning something over time: confronting a challenge and making progress."
These two mindsets have a very high impact on your life: you stay as you are, in your fixed mindset, or you grow and change and develop through your growth-mindset.
Carol shows the fundamental consequences for your own life and for the life of your (direct) environment, in sports, in education, in leadership and management.
Try to imagine your direct work/life environment, the people you meet everyday, and your own thoughts, attitudes and actions, of course, while reading the next lines.
