子曰：“不知命，无以为君子也；不知礼，无以立也；不知言，无以知人也。”
孔子说：“不懂得客观规律，就不能做君子；不懂得道德规范，就无法建功立业；不懂得分辨言论，就不能了解人。”
预测未来的最好方法就是创造未来。
Happiness is the very nature of the self; happiness and the self are not different. There is no happiness in any object of the world. We imagine through our ignorance that we derive happiness from objects.
