痛苦是暂时的，但放弃是永远的。

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.

没有付出，就没有收获。这是我的生活信条。

"The line between hero and villain is often thinner than we think."
