Here is GK Chesterton's little poem to pessimists... Introduced in his own words.
"Forgive me if I say, in my old-world fashion, that I'm damned if I ever feel like [the Hollow Men] ... I knew that the world was perishable and would end, but I did not think it would end in a whimper, but, if anything, with a trump of doom ... I will even be so indecently frivolous as to burst into song, and say to the young pessimists:
Some sneer, some snigger, some simper;
in the youth where we laughed, and sang.
And they may end with a whimper
But we will end with a bang."
