The basic law of Cologne:
§1: Et es wie et es.
(„It is how it is.“)
Look the facts in the eye, you can't change them.
$2: Et kütt wie et kütt.
(„It'll come as it comes.“)
Accept the inevitable, you can't change fate.
§3: Et hätt noch emmer joot jejange.
(„Everything turned out fine in the past.“)
What turned out okay yesterday, will still work tomorrow.
Situationally: We know it's shit, but it's the best we can do with what we have.
§4: Wat fott es, es fott.
(„What's gone is gone.“)
Don't cling to the past.
§5: Et bliev nix wie et wor.
(„Nothing ever stays the same.“)
Be open to new developments.
