《史记·七十列传·龟策列传》
预言事情，无不周全，及于自身，却被拘禁不得解脱；事情一到个人头上就无法避害趋利，要贤能本领又有什么用？
言事百全，至身而挛；当时不利，又焉事贤！
Predicting events without missing any detail, one still finds oneself tied up and unable to free oneself; once something becomes a personal affair, there is no way to avoid disasters and seek benefits. What use is it to have great abilities?
