1. 練習不幸
“It is in times of security that the spirit should be preparing itself for difficult times; while fortune is bestowing favors on it is then is the time for it to be strengthened against her rebuffs.” Seneca
經濟寬裕的塞內卡建議每個月安排幾天練習過一貧如洗的生活：只吃一點東西、穿我們最差的衣服、遠離我們家中的舒適之處。毫無保留地面對這些匱乏，問自己：「這是我之前畏懼的嗎？」
