I stopped reading marketing books for takeaways

For a long time I read marketing and business books the way I was taught to read for school: looking for the three takeaways, the underlined sentence, the thing I could repeat in a meeting to sound like I’d done the reading. It’s an efficient way to collect opinions. It’s a bad way to actually get better at anything.

What changed it was noticing how often I’d cite a “rule” from a book without being able to explain why it held — which meant I couldn’t tell when it stopped applying. A framework I can’t rebuild from scratch isn’t really mine; it’s just borrowed authority I’m renting out in meetings.

Now I read slower and closer to the argument itself — trying to reconstruct the logic well enough that I could argue the other side of it, not just repeat the conclusion. It’s slower. Fewer books get finished. But the ones that do stick around longer than a quote I could’ve gotten from a summary, and they’re actually usable the next time the situation doesn’t match the book’s example closely enough for the quoted lesson to apply cleanly.

Same instinct is currently pointed at IELTS reading passages, which turns out to be good practice for exactly this: the question isn’t “what’s the takeaway,” it’s “what’s the actual claim, and does the evidence in the passage support it or just gesture at it.”
