If you do not wish to be prone to anger, do not feed the habit; give it nothing which may tend to its increase. At first, keep quiet and count the days when you were not angry: "I used to be angry every day, then every other day: next, every two, then every three days!" and if you succeed in passing thirty days, sacrifice to the gods in thanksgiving.
EpictetusGive yourself fully to your endeavors. Decide to construct your character through excellent actions and determine to pay the price of a worthy goal. The trials you encounter will introduce you to your strengths.
EpictetusWhat hurts this person is not the occurrence itself, for another person might not feel oppressed by this situation at all. What is hurting this person is the response he or she has uncritically adopted. It is not a demonstration of kindness or friendship to the people we care about to join them in indulging in wrongheaded, negative feelings.
