Julia Evans once said "behind every best practice is a horror story." If you don't understand a Best Practice, look for the horror story that inspired it. It might make the best practice make sense. It might turn out to be something that's completely irrelevant to you, and then you can feel comfortable doing a different practice instead.

I probably sound like one of those guys who is always like, “AI will never do this , or I’ll eat my hat!!” and then he has to get his stomach pumped because it’s full of hats.
