2018-11-07: 6-P in English are 5-V in German
I just realised that the 6-P rule in English (many variations, also with a different number of P’s, exist; I’ll go with “proper preparation prevents piss-poor performance”) actually translates pretty well into German as the 5-V rule: „Vernünftige Vorbereitung verhindert völliges Versagen“ (which translates literally as “reasonable preparation prevents total failure” but that’s close enough for me).
