Stupid people are dangerous.

Suzanne Collins, The Hunger Games

In the long history of the world, only a few generations have been granted the role of defending freedom in its hour of maximum danger. I do not shrink from this responsibility — I welcome it.

John F. Kennedy

The Chinese use two brush strokes to write the word “crisis”. One brush stroke stands for danger; the other for opportunity. In a crisis, be aware of the danger — but recognize the opportunity.

John F. Kennedy

A man does what he must — in spite of personal consequences, in spite of obstacles and dangers, and pressures — and that is the basis of all human morality.

John F. Kennedy

He who learns but does not think, is lost! He who thinks but does not learn is in great danger.

Confucius

I know. It’s all wrong. By rights we shouldn’t even be here. But we are. It’s like in the great stories, Mr. Frodo. The ones that really mattered. Full of darkness and danger, they were. And sometimes you didn’t want to know the end. Because how could the end be happy? How could the world go back to the way it was when so much bad had happened? But in the end, it’s only a passing thing, this shadow. Even darkness must pass. A new day will come. And when the sun shines it will shine out the clearer. Those were the stories that stayed with you. That meant something, even if you were too small to understand why. But I think, Mr. Frodo, I do understand. I know now. Folk in those stories had lots of chances of turning back, only they didn’t. They kept going. Because they were holding on to something.

Samwise Gamgee, The Lord Of The Rings

Hope is a very dangerous thing to lose.
