Ep 4: Your Brain's Reality Filter | The reticular activating system

Your brain is filtering your reality right now. Every second of every day, a mechanism called the Reticular Activating System (the RAS) is deciding what makes it into your conscious awareness and what gets screened out. In this episode, Laura goes deeper than the surface-level version most people have heard and reveals what the RAS actually means for how you experience your life. You'll learn why nobody has ever seen unfiltered reality, why what you believe to be true is a filter set to find evidence of that truth, and you'll experience the RAS working on you in real time before the episode is over. This episode covers: What the RAS actually does and why it goes far beyond "focus on what you want" Why your brain must filter, and what would happen if it couldn't All the things that exist around you right now that you will never perceive Why your entire experience of reality is a construct built by your brain's filter An interactive exercise that demonstrates the RAS working on you in thirty seconds How your beliefs, experiences, and wiring are programming your RAS to confirm what you already think is true A live RAS activation you'll carry with you all week (hint: yellow flowers) Part 1 of 2. Next week: how to actively reprogram your RAS Connect with Laura: Instagram: @think.laura Join Laura's Free Thinking Practice on Substack: ThinkLaura

Ep 3: How Your Brain Got Wired

Before you can change how you think, you have to understand how your brain became YOUR brain. In this episode, Laura walks you through the remarkable story of how your brain wired itself. From the galaxy of neurons you were born with, to the million-plus connections forming every second in your early years, to the pruning process that shaped you into the specific person you are today. You'll learn why your emotional system had a decades-long head start on your logical mind, why your patterns feel so deeply "you," and why the same mechanism that built those patterns is the mechanism that can reshape them. This episode gives you the biological context for everything we've been practicing, plus a powerful new tool for the week ahead. This episode covers: Why you should listen to concepts you've already heard before The incredible pace of early brain development How pruning works and why "use it or lose it" shapes every part of your wiring How your earliest emotional patterns (connection, distress, disappointment) got wired based on what worked in your environment Bottom-up brain development: brainstem, limbic system, prefrontal cortex Why the amygdala (your brain's special-ops security guard) sounds the alarm before your conscious mind catches up What toddler melt downs can teach us about ourselves The decades-long head start your emotional system had on your regulatory system A quick and powerful tool to use this week to start rewiring your 'stories' Connect with Laura: Instagram: @think.laura Join Laura's Free Thinking Practice on Substack: ThinkLaura

Ep 2: Your Brain's Operating System

Before you can change how you think, you need to understand the system you're working with. In this episode, Laura covers the four primary directives your brain is running at all times: seek pleasure, avoid pain, conserve energy, ensure safety. She breaks down why this factory-installed operating system explains so much of the behavior we get frustrated with ourselves about. You'll also learn why this base system is only one layer of what your brain can do, and you'll get a simple practice to start recognizing the operating system in action this week. This episode covers: The four directives of your brain's basic operating system Why seeking pleasure was an evolutionary survival mechanism (and why that system misfires in the modern world) Why your brain automates patterns regardless of whether they serve you The difference between your basic operating system and your higher capabilities A simple weekly practice: name the directive, appreciate the biology Connect with Laura: Instagram: @think.laura Join Laura's Free Thinking Practice on Substack: ThinkLaura
