元素周期表没有改变，但我们使用其元素的方式必须改变。
A sober looks shows that just have the world gotten to be a better place after all; it is also grown a bit worse at the exact same rate.; a one step up, a one step back sort of cosmic balance between forward progress, and cultural retreat, that puts man kind on a bell curve of existence.
If you don't know where you are going, any road will get you there.
领导力意味着今天做出艰难的决定，为更美好的明天铺平道路。
