If you don't wish to be a hothead, don't feed your habit. Try as a first step to remain calm and count the days you haven't angry. I used to be angry every day, now every other day, then every third or as 30 days, thank God! For then obliterated. when you can say "I didn't lose my temper today, or the next day, or for three of four months, but kept my cool under provocation,' you will know you are in better health.

- Epictetus, Discourses, 2.18.11b-14
