Wise words!
I do have a similar mindset, to portray this I have a particular time of the day I have this realization even more effectively, that is sunset. I love being with nature, especially when I feel low or alone. During the sunset, it shows that its departure is not permanent, its departure started the countdown for another arrival, with a new day to start anew. Today's sunset is the reason for tomorrow's sunrise, so instead of getting low on the problems, I try to look for a solution ahead of it.

When someone else sees the gross darkness of the night, someone else may see it as something preceding the dawn.

True,
When some people kneel down then others start running from there and acquire fruitful results. The first one sees it as a block with nowhere to go, and the second one breaks through the blockage and makes his own way toward success. Well written, a great lesson can be acquired, if implemented properly then we may deal with things a little better.
