上天把我的命運託付給我自己，不能掌控自己的人就沒有自由。一個人的快樂取決於外在因素愈少愈好，當他知道自己該往那走時，地球隨之彎轉讓他通行。“God has entrusted me with myself. No man is free who is not master of himself. A man should so live that his happiness shall depend as little as possible on external things. The world turns aside to let any man pass who knows where he is going.”

“God has entrusted me with myself. No man is free who is not master of himself. A man should so live that his happiness shall depend as little as possible on external things. The world turns aside to let any man pass who knows where he is going.”
– Epictetus, Philosopher
