Make no mistake about it: Computers process numbers - not symbols. We measure our understanding (and control) by the extent to which we can arithmetize an activity.

卓越不是一种行为，而是一种习惯。

把自己的精神，培养得清净明澈；把自己的思想，澄清专一；把自己的胆识，培养得深沉敏捷；把自己的气魄，培养得坚强宏大；把自己的才干，培养得果敢决断；把自己的器量，培养得端正庄重；把自己的胸襟，培养得豁达宽容；把自己的节操，培养得严肃冷峻。

The most important decision is your attitude towards the world.
