This is a quote from Frank Bruni in his opinion column from here. You'll find it about 3/4 down the column in the section
titled On A Personal Note.
"But there are more good days. Many, many more. My ability to focus on that sharpened when my vision blurred.
That’s one of the mercies of how we humans are constructed. We often find perspective when we need it most."
(The italics are mine.)
I believe that is we could really step back far enough, we might discover that so much of what we humans think of as important in this world, is not.
I began to get a sense of that when I saw videos like these on YouTube:
How the Universe is Way Bigger than You Think
Cosmic Eye
A Reason to Stop Worrying...
perhaps I'll expand on this...
