For instance, consider goals. Dweck says they come in two varieties—performance goals and learning goals. Getting an A in French class is a performance goal. Being able to speak French is a learning goal. “Both goals are entirely normal and pretty much universal,” Dweck says, “and both can fuel achievement.”8 But only one leads to mastery. In several studies, Dweck found that giving children a performance goal (say, getting a high mark on a test) was effective for relatively straightforward problems but often inhibited children’s ability to apply the concepts to new situations.
