Eisenberger’s research again supports Duckworth’s hypothesis that children can develop grit by participating in challenging, structured activities—even if they only start these activities because of parental pressure. Of course, Duckworth has already shown that all the components of grit—interest, practice, purpose, and hope—are learnable. But, in one way or another, commitment and hard work are foundational to all of these elements: people have to commit in order to develop their interests, build a routine of deliberate practice, find a sense of purpose in their work, and learn to approach setbacks with optimism. Thus, by showing that industriousness is learnable, too, Duckworth affirms that it truly is possible to build grit from the ground up.
