Of the many valuable lessons found in Harry Potter, perhaps the most important throughout adulthood is that choices make the man. J.K. Rowling's characters each struggle with issues in their respective pasts, but determine their own destiny through life choices. Harry guides his own wizarding adventure from the very start, when he insists that the Sorting Hat place him in a Hogwarts house other than Slytherin. His academically driven friend, Hermione Granger, becomes known as "the brightest witch of her age" despite her non-magical background. Many other examples of this idea can be found within the pages of Rowling's seven novels, and it serves to show readers of all ages that your actions mean more than your past.
