How is title of the novel "Persuasion" an appropriate one?

Persuasion is a novel about second chances.  It was Jane Austen's last work.  She wrote it during her illness which led to the end of her life at the young age of 42.

Jane Austen, was perhaps thinking about her own life when she wrote Persuasion, about her missed chances at love and marriage. About the nature of relationships in her society, and how love was secondary if allowed in the decision to marry at all.  I think the examination of Austen's society in this book is very thorough and insightful. 

Jane Austen reminisces in this book and as always, gives her characters a chance to find each other again, a chance that she did not have herself in her lifetime. 

The title of the book is very appropriate.  Jane Austen has succeeded in persuading the reader that love in marriage does matter and that life is about second chances. All her books teach the reader, Persuasion, as her last, gives us that happy ending that we so crave, along with Jane, who did not succeed in attaining for herself.  But she never disappoints with her characters.
