A sound of thunder tho i am not very sure why this one
Duckworth’s experiences as a teacher-led him to observe and understand that the difference between the students wasn’t just their intelligence, but more than just that.
<em>Explanation</em>
When Duckworth was teaching the seventh graders Maths, he observed that the most intelligent of the kids in his class weren’t smart enough otherwise, and the ones less intelligent were smarter than the ones who scored a higher IQ.
This observation of his is what drove him to start studying further and become a psychology student, thus studying the matter in depth.
He went ahead to study the matter further by conducting longitudinal studies as to who would be able to stick around more and be successful in their respective field.
His final conclusion was that people who had the "grit" to stick around and have the consistency to pursue things were the one's who were more successful and were able to achieve their dreams.
