Sometimes you just keep going.
Why? Probably it's what Berra learned from doing what he did in baseball.
If you don't move down the road, maybe it's because you don't know where the road might be taking you. Even so, take a step, then another, and see whatever is there to see -- the yellow line, cracks in the road, rocks along the side, or maybe the foliage as you look beyond the trees and wonder where you are going.
Here's a remark for you to remember:
"A person often meets his destiny on the road he took to avoid it," said Jean de la Fontaine, 17th Century French poet whose fables are still quoted nowadays.
Ayn Rand said, "People create their own questions because they are afraid to look straight. All you have to do is look straight and see the road, and when you see it, don't sit looking at it -- walk."
Okay, if you're tired, you can't help recalling other long walks that led to empty spots and dead-end places, dark places -- where time was wasted looking for ways to get out, or ways to back out while traveling slowly backwards.
Hey, even moving backwards you are progressing. Back, sideways, forward, or up or down is progressing -- it's life's exercise.
You could quote Hawking, Einstein, Margaret Thatcher, Buddha -- a lot of major thinkers talk about the roads we travel on. You could sing that song:
"Life is a winding road,
with many twists and turns.
You must make the right choices,
or you will crash and burn.
There is always a chance,
the wrong choice will be chosen.
But do not fret, and do not fear.
The right choice you will hear.
Life is a winding road,
with many different choices.
Be careful what you choose,
for there are many different voices."
Yes, sing but don't judge, attach praise, or fears, or definitions. Be there. Just be there as you go.
