Maybe Not Ever Enough

Terse lines seem to represent themselves fully 
Confident that no more could be added 
Might a life of any sort find itself with the same concise 
answers to the question of how long? 
Even those terse lines wonder if they've gotten their point across 
A hundred years will always wonder 
About the first day of the next century 
A novel begging for a sequel 
The sequel a trilogy 
And the trilogy a prequel 
For more days can come 
From either side 
As long as they're added 
To this unquenchable thirst 
So no optimization 
Could meet the parameters 
Of bacteria 
That can't be enough 
Of organs 
That's can't be played enough 
A concert that could go on forever 
Playing until the ears ran out 
Would want a little more
