战争是可怕的，但不是最可怕的事情；道德和爱国情感的衰败和堕落，认为没有什么值得战争，更糟糕。
War is an ugly thing， but not the ugliest of things； the decayed and degraded state of moral and patriotic feeling which thinks that nothing is worth war is much worse.
预测未来的最好方式就是创造未来。
Be fearless in the pursuit of what sets your soul on fire.
最危险的浪费是我们没有意识到的浪费。
智者能预测未来，愚人只看现在。
无人机的未来不是替代人，而是赋能人。
