The Enchiridion – Epictetus

A classic handbook on ideal behaviour from the Ancient Greeks.  This was such a good book it has lasted in circulation almost as long as the Bible.  It is interesting to see how some of the prevailing views in society have changed from then til now, but there are many pages of good advice and ample ammo for consideration in here.  If you read this book, and enact some of its prescriptions, you will likely become a better or stronger person.
