Diana's Leadership Qualities

In this section of the book, we see Diana as the hero of the tale. She recognizes the merit of her ideas even though the upper management of Squirrel, Inc. doesn't. The current leaders of the corporation are threatened by change even though it is clear that their model of nut burying isn't working. Rather than explore new ideas, they fire Diana and cling to their old ways.

Meanwhile, Diana isn't disheartened by the firing. She realizes that even if Squirrel, Inc. isn't willing to try her way of doing things, she can find others who will. She uses the firing as a chance to start her own company. The difficult journey to the Windy City represents what it must be like to start a career. Diana demonstrates her toughness on this journey, and when she arrives she reaps her reward. Her reputation has preceded her, and the other squirrels listen eagerly as she turns her story into a motivational speech. Adversity has made her stronger.

I think Diana's sex may have caused extra difficulties for her. The upper management at Squirrel, Inc. may not have been receptive to her ideas because she is female. Even the narrator, who is largely sympathetic, expresses doubts about her ability to make the journey.
When Diana fights off the Doberman, she is exhibiting distinctly unfeminine traits. Such aggression is often admired in men but frowned upon in women. But maybe the discrimination Diana faces as a female has made her even stronger.
