Two principles we should always have ready — that there is nothing good or evil save in the will; and that we are not to lead events, but to follow them.
EpictetusIf 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.
EpictetusWe need to regularly stop and take stock; to sit down and determine within ourselves which things are worth valuing and which things are not; which risks are worth the cost and which are not. Even the most confusing or hurtful aspects of life can be made more tolerable by clear seeing and by choice.
