The hollow men V - TS Eliot

Between the idea
And the reality
Between the motion
And the act
Falls the Shadow
For Thine is the Kingdom

Between the conception
And the creation
Between the emotion
And the response
Falls the Shadow
Life is very long

Between the desire
And the spasm
Between the potency
And the existence
Between the essence
And the descent
Falls the Shadow
For Thine is the Kingdom

For Thine is
Life is
For Thine is the

This is the way the world ends
This is the way the world ends
This is the way the world ends
Not with a bang but a whimper.

I wonder why TS Eliot said life is very long. Maybe he was referring to the afterlife and yes, that would be a verrryyyy long time. But on earth, life is truly very short. Time passes so fast. Unbelievably, March is ending and a new quarter of the year will begin in a heartbeat.
There's this fear in me that time is running out. Will we ever out-run time? Hah impossible. Decisions made but concrete plans were not, needless to say the execution. How much more time do I have to waste....?
