【原文】冉求曰：“非不悦子之道，力不足也。”子曰：“力不足者，中道而废，今汝划。”【译文】冉求说：“我不是不喜欢您的学说，而是我的能力不足。”孔子说：“如果是能力不足的话，是走到中途才废弃而停止，但现在你还没开始，就给自己划了一条截止的界限而停止前进了。”

The chief beauty about time is that you cannot waste it in advance. The next year, the next day, the next hour are lying ready for you, as perfect, as unspoiled, as if you had never wasted or misapplied a single moment in all your life. You can turn over a new leaf every hour if you choose.
