“Self-Brain Surgery® is like ten years of therapy in five minutes.”

🧠 Paid Subscribers: Scroll to the bottom for this week’s video self-brain surgery training. I give you an operation to take this week’s letter into daily practice!

Hey friend,

In medicine, we teach everyone Basic Life Support, or BLS. It’s the foundational set of skills you use when someone’s heart stops or they stop breathing. You don’t need to be a cardiologist. You just need to know the basic moves that can save a life.

I want to give you something similar for your mind.

I call it Basic Self-Brain Surgery®, and today I’m going to teach you how to do CPR for your brain.

Most of us spend far too much time in brain management mode, reacting to whatever automatic thoughts and feelings our brain throws at us. But you don’t have to live there.

Basic Self-Brain Surgery® is a simple, repeatable procedure you can use anytime to quickly move from reactive brain management mode into self-brain surgeon mode, where your mind is in charge and you’re directing your brain with intention and truth.

Here’s the basic procedure. I want you to memorize it.

C: Be Curious

Most of us treat our automatic thoughts and feelings like facts. We react to them as if they’re true and important without ever questioning them. And since most people think they ARE their brains, they don’t even realize they have a choice.

Self-brain surgeons like you know better.

The first move in Basic Self-Brain Surgery® is to get curious, or even a little cynical, about what just showed up in your mind.

Instead of immediately believing or obeying the thought or feeling, pause and get ready to operate your brain so it stops operating you.

Neuroscience nugget: Your brain generates thousands of thoughts and emotional signals every day. Many of them are old predictions, emotional habits, or threat detections that were useful in the past but are not accurate or helpful in the present. Curiosity activates your prefrontal regulatory networks and interrupts automatic reactivity.

Self-Brain Surgery Procedure: The next time you notice a strong thought or feeling, say out loud or in your head: “Interesting. Let me investigate that.” This small shift moves you from patient to surgeon.

Scripture: “Dear friends, do not believe every spirit, but test the spirits to see whether they are from God…” 1 John 4:1

P: Perform a Thought Biopsy

Once you’re curious, the next step is to examine the thought or feeling more closely.

I call this a thought biopsy. You take a small sample of what you’re thinking or feeling and ask two simple questions:

  1. Is this true?

  2. Does it require or deserve a response right now?

Most of the time, the answer to at least one of those questions is no.

Neuroscience nugget: When you slow down and examine a thought instead of reacting to it, you give your higher regulatory networks time to come online. This reduces the power of automatic emotional responses and gives you more choice in how you respond.

Self-Brain Surgery Procedure: Ask yourself: “Is this thought or feeling true? And even if it feels true, does it require my attention or energy right now?” Be honest. Most thoughts don’t survive this simple test.

Scripture: “We demolish arguments and every pretension that sets itself up against the knowledge of God, and we take captive every thought to make it obedient to Christ.” 2 Corinthians 10:5

R: Replace with Truth

After you’ve examined the thought and found it wanting, you don’t just try to stop thinking it. You actively replace it with something true.

This is the “R” in CPR, Replace.

You intentionally put a true thought, a promise from scripture, or a statement of who you are in Christ in its place.

Neuroscience nugget: The brain strengthens whatever pathways you repeatedly use. When you replace a disordered or false thought with truth and repeat it, you begin to wire new, healthier patterns. Replacement is more effective than simple suppression.

Self-Brain Surgery Procedure: Once you’ve identified a false or unhelpful thought, speak or write one true statement in its place. It can be a specific scripture, an identity statement (“I am a child of God, deeply loved and secure”), or a fact (“This feeling is real, but it is not the whole story”).

Scripture: “Finally, brothers and sisters, whatever is true, whatever is noble, whatever is right, whatever is pure, whatever is lovely, whatever is admirable; if anything is excellent or praiseworthy, think about such things.” Philippians 4:8

Put It Into Practice: The 60-Second CPR Reset

Here’s a simple exercise I want you to practice this week.

Anytime you notice yourself slipping into brain management mode, feeling reactive, anxious, angry, or overwhelmed by automatic thoughts, run this 60-second CPR Reset:

  1. C: Curious Pause and say: “Interesting. What am I thinking or feeling right now?”

  2. P: Perform a Thought Biopsy Ask: “Is this true? Does it require or deserve my attention right now?”

  3. R: Replace Speak or think one true statement that puts things back in proper order.

Do this reset at least three times today, anytime a strong thought or feeling pops into your head. The more you practice it when things are calm, the more automatic it becomes when things get hard.

This is Basic Self-Brain Surgery®. It’s simple enough to use in the middle of a difficult conversation, while driving, or lying in bed at night. And it works.

I’d love to hear how the CPR Reset goes for you this week. Hit reply and let me know which part (C, P, or R) feels most helpful right now.

Where We’re Going This Week

In today’s bonus video for the paid subscribers, I’ll take you deeper into the basic self-brain surgery technique.

On tomorrow’s podcast episode, we’ll discuss the situations this is useful for, and when you might need a more specialized procedure like the ones from my new book. And then on Friday Self-Brain Surgery® on YouTube, I’ll give you a tactical operation you can use to escape brain management mode anytime you slip back into it.

I’d love to hear how these work for you this week. And if you like these “Ten years of therapy in five minutes” posts, hit reply and let me know you want more of them.

With you on the journey, friend!
