Yes, there will be moments like these, my friend. When it becomes a struggle to rip thoughts from the maw of your seething brain and forge them in flame, shaping them into words with meaning.
There will be days it becomes an insurmountable challenge to excavate ideas from the depths of your psyche and build them into a shining palace of lucid thought and revelation.
When the tasks, the stresses and worries of the day spill past the rim of your Vessel of Hours. A slow trickle at first. Then a deluge, a flashflood that sweeps you beyond the Doorway to Sanity. And Life slams the door on your fingers as you claw your way back.
Even on those days, you can find something good to say about your writing.
“Thank the heavens I decided to skip NaNoWriMo this year!”
