I'm not afraid of storms, for I'm learning how to sail my ship.

I'm not perfect, but I strive for perfection.

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.

千里之行，始于足下，再近的道路，如果你不走，就永远不能到达；一屋不扫，何以扫天下？再小的事情，你都不去做，何谈成功？
