How do we believe in a God that we don't get to see, but have made a conscious choice to follow. The people who actually survived during the 2WW generally have a God they cling to. It is very much a matter of mind over matter.
But we are not at war. We have a mundane life if not so mundane jobs. I mean, this picture is so appropriate. Here we thought we are okay, if not perfect. But there is always someone or something which will spoil the perfect life or picture we want to have.

So the moral of the story?
The happiest people don't necessarily have the best of everything; they just make the best of everything they have. Life isn't about how to survive the storm, but how to dance in the rain.
(not sure who wrote the observation, but serves as a useful reminder)
