The best decisions aren't made with your head, but with your heart.
最好的决定不是用头脑做出的，而是用心做出的。
The end of history will be a very sad time. The struggle for recognition, the willingness to risk one's life for a purely abstract goal, the worldwide ideological struggle that called forth daring, courage, imagination, and idealism, will be replaced by economic calculation, the endless solving of technical problems, environmental concerns, and the satisfaction of sophisticated consumer demands.
The power of causal reasoning is that it allows us to predict the effects of actions we have never taken.
