"This is a list of 100 books that deal, somehow, with happiness. There's a huge amount of variation on this list. The non-fiction books are more straightforward—many of them are self-help books that deal directly with happiness, helping to organize a life around a positive center, while others are memoirs that reflect on mental health and how to make your way towards a successful ending.
The fiction section varies more wildly. This isn't a collection of happy books, but of books about happiness, and many of the books there, recommendations from both me and crowdsourced from friends and fellow Rioters, deal with rough topics of mental health, the lack of acceptance, and looking for happiness in all the wrong places. But all of them deal with happiness—whether that means contentment, a journey, satisfaction, or adventure."
