From a BYU Devotional by Jennifer B. Nielson:
Dweck has proposed that there are two basic mind-sets: a growth mind-set and a fixed mind-set.11 The assumption of those with a growth mind-set is that intelligence, creativity, artistic ability, or other traits are flexible, not frozen, and that they can increase with continual practice. The assumption of those with a fixed mind-set is that traits are inherent and cannot be changed.
