Older, but no wiser

At peace... sort of, a relative peace...
After months of all systems flat out,
striving, straining, hoping, wishing…
it looks like I finally found the off switch.
Or it found me.
Must’ve got knocked accidentally in all that banging up against obstacles.
It’s nice to rest awhile, to coast along with the engine off.
(Makes it difficult to write anything though, with the source of motive force shut down).
Good job too it’s quiet here where I’m sat…
Just hope I can find the on switch again when the time comes. Before I grind to a complete halt.

When the time comes?
What time would that be then?
