Old is gold?

Today I thought
I'd be narcissus.

Read my own lines
To slake the thirst

To read a decent word or two
That wasn't asking me to

Politely take some urgent action
To expedite some interaction,

Or ask some party to
Fulfill a clause they agreed to..

Even as my feeble words satisfy the drought
I am troubled by this peculiar thought

"Each line I write today
Seems duller than the one I wrote yesterday

Was I better at words earlier?
Or tis Posterity that makes it so appear?"
