Catherine McMahon Posted 6 months ago Angela Lee Duckworth: The key to success? Grit Hello Alejandro - I agree with you - in part - but although children raised in the same family are different so are their personal responses to events. Human beings are endowed with freedom. They are able to choose to decide not to decide. My brother may decide one thing and I may decide another but that's not simply and only my DNA, that is also my intellect, will and emotions. Otherwise there would be no right or wrong, no accountability for our actions, no personal responsibility; it would simply boil down to your biological makeup. And that would mean there would be no need for any court of justice, no need for psychologists to help people to rectify or improve, no need for education. What do you think?
