Write what you know:

Niemand ist mehr Sklave, als der sich für frei hält, ohne es zu sein.
—Johann Wolfgang von Goethe, Die Wahlverwandtschaften (1809).

Alles ist das, was du daraus machst, auch du selbst.
—Joseph Goebbels, Michael: ein Deutsches Schicksal in Tagebuchblättern (1929).

Colorless green ideas sleep furiously.
—Noam Chomsky, Syntactic Structures (1957).

Write what you know.
Write what you know.
Write what you know.
Don't leave your torso.

Write what you know.
Write what you know.
Write what you know
with piss on the snow.

Write what you know.
Stale tobacco.
Pistachio.
That one talk show.

Sweet potatoe.
Negative cash flow.
Cheap ass merlot.
Cigarette glow.

Right what I know—
I dunno. I dunno.
I dunno what I know.
Write what you know.

Write what you know.
Write what you know.
Hell if I know.
Seeds must crack to grow.
