Once & again

"Once and again, time does own us,
But now and then, we seem to be in control
If we fail to observe
(...)
If we feel the urge
We must react

Yet, this is not intricate, it's simple
And in simple things, would you prefer...
A hard climb or free fall?
To be on top or below ?
A U-turn or a U-Haul?
To learn or to know?

To be, to feel, to see... and comprehend.
The gain without pain exists...
Once and again

(...)"

      in "Once & Again, just now.

This was an incomplete train of thought.
Maybe it will develop into something.
