Reddit mentions of Stoicism and the Art of Happiness: Practical Wisdom for Everyday Life (Teach Yourself)

Here is my short list of books that I usually recommend as starting points (most of these are found in the FAQ as well):

• Stoicism by John Sellars is an introductory-level academic overview of Stoic philosophy and is a solid introduction to the subject.
  
  
• Stoicism: A Very Short Introduction by Brad Inwood is another broad overview by an academic scholar of Stoicism, but it's much more condensed. Very informative, however.
  
  
• Stoicism and the Art of Happiness by Donald Robertson is a practical introduction on what Stoicism is and how to implement it in your life.
  
  
• Epictetus - Discourses, Fragments, Handbook translated by Robin Hard is a book containing the lectures of the Stoic teacher Epictetus. He was the most influential Stoic philosopher of his age, and his Discourses were studied by the famous Roman emperor and Stoic philosopher Marcus Aurelius. (The "Enchiridion" is included in this collection as well, also called the "Handbook".)
  
  
• Seneca's Dialogues and Essays, especially the essays "On The Shortness of Life" and "On the Happy Life" and Letters from a Stoic contain Seneca's useful writings on a number of topics and is another popular place to begin learning about Stoicism.
  
  You can also check out the IEP entries on Stoicism and Stoic Ethics if you'd like to start with briefer reading first.
  
  Finally, there are a number of videos on Stoicism and related topics that you may find helpful. (But of course books go into more depth than short videos can.)
