Self-pity” is just sadness, I think, in the pejorative.
The dishes that were meant to be hot were never quite as warm as those that were meant to be chilled.
That ‘writers write’ is meant to be self-evident. People like to say it. I find it is hardly ever true. Writers drink. Writers rant. Writers phone. Writers sleep. I have met very few writers who write at all.
I think when you are truly stuck, when you have stood still in the same spot for too long, you throw a grenade in exactly the spot you were standing in, and jump, and pray. It is the momentum of last resort.
