Other people's views and troubles can be contagious. Don't sabotage yourself by unwittingly adopting negative, unproductive attitudes through your associations with others.
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.
EpictetusLampis the ship owner, on being asked how he acquired his great wealth, replied, My great wealth was acquired with no difficulty, but my small wealth, my first gains, with much labor.
EpictetusYou can be invincible, if you enter into no contest in which it is not in your power to conquer.
