The Stoics: Negative Visualisation III

“When you are going to perform an act, remind yourself what kind of things the act may involve. When going to the swimming pool, reflect on what may happen at the pool: some will splash the water, some will push against one another, others will abuse one another, and others will steal. Thusly you have mentally prepared yourself to undertake the act, and then you can say to yourself: I now intend to bathe, and am prepared to maintain my will in a virtuous manner, having warned myself of what may occur.”

– Epictetus
