Which character in the book shows that learning to love yourself for your uniquness is the greatest lesson of all.

I think that Mole does the most self-discovery in the book. Given to mood swings of happiness, depression, and rashness, Mole is a kind-hearted little mole whose distaste of spring chores sets off the adventures of the novel “The Wind in the Willows” by Kenneth Grahame. He goes barreling through the sunlight, meeting and becoming friends with Rat, with whom he becomes roommates. Mole is happy to meet Otter, Badger, and Toad, all in due course. Mole has his own moments of foolhardiness and rashness, such as when he rushes into the Wild Wood without a second thought just before a snowstorm hits. By the end of the story, Mole is much more self-aware than he has ever been and has a new appreciation for bot his strengths and his weaknesses.
