The Boston Globe had an article two years ago called, "The Truth About Grit". Unfortunately, it is not available for free anymore. But, it remains one of my favorite articles. As a mom of a child that is 2-E and one that is neuro-typical/ average, I am heartened that they can be successful due to their stick-to-it-ness, work ethic and goal setting. These are not things I taught them - but traits they inherited largely from my husband's family.
I like what inky says - talent is only the starting point.
Thanks for posting.
