Confidence is key, but you have to back it up with skill.
自信是关键，但你必须用实力来支撑它。
The dead are not gone; they are part of us.
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 choice is simple: either we protect nature now, or we pay the price later.
