I asked ChatGPT to use Charlie Munger’s ‘Inversion rule' to rethink my goals — and it beat every productivity app

For years, I approached my goals the same way most people do with a forward-thinking approach. I have kept a journal with ChatGPT with both daily goals and long term aspirations, so each day started by asking myself average questions like, how do I get more successful and the big one, how do I make more money? At the same time, I've always tried to focus on my mental health to stop stress before it starts.

But then I came across one of the most famous mental models from the late billionaire investor Charlie Munger: “Invert, always invert.” For anyone new to Charlie Munger, he’s well worth discovering. I did a deep dive with NotebookLM on his rules for goals and his approach to mindset, which included learning across multiple fields, often drawing from math, philosophy and psychology to better understand how the world works and make smarter decisions.

Munger believed that many of life’s hardest problems become easy when you flip them upside down. Instead of asking how to win, you ask how to lose and then you ruthlessly avoid those mistakes.

I decided to run an experiment and try his "Inversion Rule." I stopped asking ChatGPT for "success tips" and started using it as a brutal, unbiased auditor of my own failures. Since I keep memory mode enabled, the AI knows me well enough to be of assistance.

What is the Inversion Rule?

The concept is deceptively simple. Most people focus on the "plus" side of the equation (adding habits, adding tools). Inversion focuses on the "minus" (removing stupidity).

So instead of asking ChatGPT questions like, "How do I become successful?" or "How do I become happier?" the rule suggests asking questions such as "How do I guarantee failure?" and "How do I ensure I say stuck exactly where I am?"

Not going to lie, asking those questions gave me the "ick" because I am always such a positive and forward-thinking person. But ChatGPT made me see my own behaviors as "success killers" and it was the reality check I needed.

Here's what happened when I asked those questions to AI.

I used AI to 'Invert' my work life first

ChatGPT knows my daily schedule because I have all my apps connected to it using the ChatGPT app hub. From Slack to Gmail, the AI keeps me organized. But for the sake of trying this rule out, I also uploaded my calendar and my "To-Do" list. Then I used the following prompt: "Use Munger’s Inversion Rule to tell me how someone with my skills stays underpaid, stressed and overlooked.”

Unlike a friend who wants to spare your feelings or sugar coat things, AI didn't hold back. Within seconds, it mapped out my "Strategy for Failure" that looked like this:

• Tie self-worth to daily metrics: Ensure your mood is dictated by a graph you don't fully control.
• Wait to be recognized: Never create "leverage" or your own products; just keep building on someone else’s platform.
• The 'maintenance trap': Spend 80% of your energy on short-term deadlines and "reactive" tasks.
• Strategic drift: Work incredibly hard, but never on one thing for long enough for it to compound.

Seeing my "hard work" reframed as "strategic drift" was the uncomfortable truth I needed. I realized I didn't need a better calendar app or more productivity tools; I needed to stop choosing comfort over progress.

Then, because I'd already been slapped on the figurative cheek, I used a version of that prompt on stress. It looked like this: "How would I guarantee total burnout by the end of the month?"

Again, the answers were immediate and familiar:

• Check metrics and Slack immediately upon waking.
• Compare your "behind-the-scenes" to everyone else’s "highlight reel."
• Say yes to every "quick call" or low-priority request.
• Never rest without a side of guilt.

This was wild for me, and if you try it, you'll understand why. Once you see these behaviors as a deliberate plan for misery, they become much harder to justify. It’s no longer "just a bad habit," but a choice to fail.

Removing sabotaging habits

Without AI, I probably wouldn't have been able to do such a deep dive into Charlie Munger's thought models, at least not in a single evening. NotebookLM gave me the background I needed to then ask ChatGPT how to implement those rules and strategies. I probably would have considered them but ChatGPT gave me a mental visual because it knows my habits almost better than me.

In other words, I used AI as a Cognitive Filter. By inverting my goals, I found my "fake priorities." I thought I needed to do more. Inversion showed me I needed to do less:

• Fewer reactive tasks: If it doesn't move the needle, it's a distraction.
• Fewer emotional decisions: Stop treating every slow day like a disaster.
• Fewer comparisons: Focus on my own "compounding interest" in my work.

Try this prompt yourself: "I want to apply Charlie Munger’s Inversion Rule. I am currently focusing on [Goal]. List the top 10 behaviors that would guarantee I fail at this goal over the next six months. Then, analyze my current habits and tell me which of these traps I am currently falling into."

The takeaway

This experiment was energizing because I had never seen this perspective until now — and never one that was quite so "spot on" and personal. Having AI call you out on your bad habits is humbling, let me tell you. I was not expecting to enjoy the results of this test or go "all in" on this rule, but it helped me realize that a lot of "hard work" is really just strategic drift.

The mindset shift also was helpful with stress, too. I asked what habits would guarantee burnout so they could be stopped before they spiraled.

If you give this prompt a try, let me know in the comments. I'd love to know how it worked for you.
