The future belongs to those who believe in the beauty of their dreams.

The hardest challenges often lead to the greatest breakthroughs.

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.

Quality is not a destination; it is a journey.

你必须努力才能到达顶峰，但你必须更加努力才能留在那里。
