In fact, in traditional Chinese thought--Buddhism, Taoism, Confucianism--and even in Christianity, doctrines of self-cultivation and health all urge humility and adapting calmly to adversity. There is no great difference between these ideas and the author's definition of "positive thinking."
其實，中國的儒、釋、道，乃至西方的基督教，在修身養性的教諭上，都有要人謙卑、逆來順受的觀念，這和作者所定義的「正面思考」並沒有太大的差別。
