Writing, Some Days, Seems Like a Task Insurmountable

Writing, some days, seems like a task insurmountable.
We chase the muse of inspiration,
we attempt to think a thought so extraordinary that our words simply appear

The act of writing seems as it were

When there is no muse whispering thoughts of enlightenment,
how impossible the act seems
to even begin.

Hours and days are spent looking,
staring and the blank page reflecting
a mind so blank and hungry for ideas.
On days like those, one singular question, one notion,
Both plagues the mind and darkens the soul...
'Where do I even begin?'
The question repeats incessantly.
Hours spent searching....
the mind seeking to gorge itself on every bit and byte of information it can hold
but still nothing.
Is the problem in the mind?
Or is this a symptom of a constipated soul?
