I had a tech startup superstition of my own: When a founder asks you to write answers on a FAQ page or knowledge base in response to questions that have never actually been asked by a customer yet, the startup will fail.

Based on a similar philosophy about detached thinking at the top, and how it sinks companies. Answers to customer questions should only be posted after they've been asked at least once, otherwise it's a sign the founders are daydreaming about customers with problems that don't exist yet
