From “Mindset: The New Psychology of Success” by Carol S. Dweck, PhD
From the point of view of the fixed mindset, effort is only for people with deficiencies. And when people already know they’re deficient, maybe they have nothing to lose by trying. But if you claim to fame is not having any deficiencies – if you’re considered a genius, a talent, or a natural – then you have a lot to lose. Effort can reduce you.
