"I wonder how many people have ever thought to blame their own failures on "not hanging in there long enough"? In my experience, very few. Instead, we assume we lack the ability to succeed. We decide that we don't have what it takes — whatever that is — to meet the challenge. And we really couldn't be more wrong. Grit is not an innate gift. Persisting is something we learn to do, when (and if) we realize how well it pays off."
