Answer:
The author gives Rowling's example because JK Rowling's inspirational story illustrates the author's point that 'Goals Need Grit'
Explanation:
The author wanted to give an example of illustrating how grit, or persevering in the face of obstacles, will allow you to get past those obstacles. Harry Potter is one of the all-time best selling books that quite literally pushed JK Rowling to the pinnacle of fame of success. Her journey was not easy in the slightest. She lived a difficult life before achieving incredible success as highlighted by the author. Writing a top selling series is not easy and when she came up with an idea of writing a book, she spent years working on it only to be declined by the publishers who felt that her feminine name would hamper book sales. This is a point where most people would give up out of sheer frustration. However, Rowling moved passed this as well. Her pashion for her work, her determimation and her perseverance allowed her to come up with an interesting way to put her name on the book and get away with it. As we all know, this worked brilliantly.
Therefore this example, illustrating Rowling's grit, her pashion, and her fierce desire to push past obstacles, shows how you need grit to overcome problems and achieve your goals.
