我现在承担了一项严肃的任务，恐怕这个任务超出了任何人的能力范围。

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.

If you’re not failing occasionally, you’re not pushing the boundaries enough.
