Stealing.

There are times when your fingers cramp like an arthritic zombie making snowballs.

There are times when your brain freezes like a pigeon in a hail storm.

There are times when deadlines hit like Hiroshima.

You have to learn from those times. 
And learn to write through them.
Sometimes I take a walk.
Sometimes I shoot the shit.
Sometimes I read Raymond Chandler or Dashiell Hammett or Graham Greene or Ring Lardner or Damon Runyan and hate myself for not being them.

And to everyone who's ever "ghosted" you, there's this from Shirley Jackson.
