Meaning
It means you should extract a repeatable principle from every single problem you solve. Don’t just fix it and forget it.
Explanation
Look, here’s the thing I’ve learned the hard way. Most of us, we solve a problem and we just move on. We’re relieved it’s over. But that’s the biggest missed opportunity. The real gold isn’t in solving the problem once. It’s in never having to solve that same type of problem again. You have to actively ask yourself, “Okay, what was the core lesson here? What’s the underlying rule or pattern?” That rule becomes your personal algorithm, your secret weapon. It’s how you stop being a firefighter and start being a fire marshal.

Usage Examples
- For a Project Manager: A project derails because of poor communication. The solved problem is getting it back on track. The rule you extract? Implement a mandatory weekly 15-minute sync for all team leads. That rule saves the next ten projects.
- For a Developer: You spend a day fixing a nasty bug caused by a race condition. The solved problem is the fixed bug. The rule? Always implement mutex locks when these two services interact. That rule saves you dozens of future debugging headaches.
- For a Marketer: A social media post flops. The solved problem is deleting the post. The rule? Our audience engages 70% more with video tutorials than with static infographics on this platform. That rule shapes your entire content strategy moving forward.

FAQ
Question: Isn’t this just common sense?
Answer: It is, but it’s uncommonly applied. Common sense would be to be happy the problem is gone. This mindset forces you to do the extra cognitive work to mine the lesson.
Question: What if the problem is a one-off, unique situation?
Answer: I used to think that too. But there’s always a rule, even if it’s a broader principle like Always get sign-off from Legal on campaigns involving user-generated content, which you learned from that one, unique legal nightmare.
Question: How do I find the time to do this for every single problem?
Answer: You don’t need a formal report. It takes 30 seconds. Just ask, What’s the one thing I should do differently next time? and jot it down. The ROI on that 30 seconds is massive.
