in three words...

In three words I can sum up everything I've learned about life: it goes on. (R. Frost)

fire and ice

Some say the world will end in fire,

Some say in ice.

From what I've tasted of desire

I hold with those who favor fire.

But if it had to perish twice,

I think I know enough of hate

To say that for destruction ice

Is also great

And would suffice.

(Robert Frost)
