"Life is either a daring adventure or nothing at all."

成功经济发展的关键在于获得正确的价格并创造正确的激励。

可持续的世界始于可持续的选择。

The only wisdom we can hope to acquire is the wisdom of humility: humility is endless.

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.
