Don't be concerned with other people's impressions of you. They are dazzled and deluded by appearances. Stick with your purpose. This alone will strengthen your will and give your life coherence.
EpictetusDo you know that disease and death must needs overtake us, no matter what we are doing?... what do you wish to be doing when it overtakes you?... If you have anything better to be doing when you are so overtaken, get to work on that.
EpictetusIf you do not wish to be prone to anger, do not feed the habit; give it nothing which may tend to its increase.
