The Enchiridion, or Handbook of Epictetus, often shortened to simply "The Handbook", is a short manual of Stoic ethical advice compiled by Arrian, who had been a pupil of Epictetus at the beginning of the 2nd century.
Although the content is derived from the Discourses of Epictetus, it is not a summary of the Discourses, but rather it is a compilation of practical precepts. The Handbook is a guide to daily life. Unlike some of his forefathers in Greek philosophy (i.e. Plato and the other metaphysicians), Epictetus focuses his attention on how to practically apply oneself on a philosophical level. The primary theme in this short work is that one should expect what will happen and wish it to happen so.
