I've been building the next classroom course this week, and it kept circling back to one question. turns out it's the hardest one to answer and the most valuable. not "what do you do." what must never happen in your work? here's why that matters more than it sounds. an agent can look up almost anything about your field. the standards, the formulas, the vocabulary, the best practice – all of it is a search away. what it cannot look up is the rule you learned by watching something go badly wrong. so it will break that rule. cheerfully, confidently, probably in the first week. and you're the one who signs off on the output. the fix is almost stupidly simple: write the rule down once, somewhere it reads every session. most of these rules are under ten words. the one I keep coming back to – never present an estimate as a quotation – is seven, and it prevents an entire category of expensive mistake. no amount of general intelligence gets you that. you only get it from someone who has watched it go wrong. so, one line in the comments 👇 what must never happen in your work? mine: never a number without its source. unverified figures don't go into research, and a sourced one takes ten seconds to check instead of an afternoon. and a few of you I'd genuinely like to hear from, because I have a guess: @Uzair Nazeer – LN app creation?. what's the reading you'd never act on without checking twice? @Amy Zinserling – what would you never say in a session, no matter where a client takes it? @Tim Adams – what would you never put in writing to a prospect? @Monosriz Dutta – twenty years of transformation work. what's the shortcut that always costs more than it saves? @Joao Carvalho – you publish weekly now. what would you never let go out under your name? wrong guesses welcome – correcting me counts as an answer 😄
