Why your brain resists change and what to do about it

Your brain isn’t lazy; it’s wired for survival. These 3 science-backed strategies will help you stop productive procrastination and start making real moves.

A few years ago, I sat across from a mentor and told her I wanted to launch a company.

I had the data. The drive. A product I believed in.

But instead of taking the leap, I found myself rewriting pitch decks, reading books on entrepreneurship, and organizing my desktop folders. Productive procrastination at its finest.

Looking back, I wasn't lazy. I was afraid. My brain was doing exactly what it was designed to do.

Change feels threatening to the brain, even when we want it.

Why? Because our brains are hardwired to favor familiarity. That instinct kept our ancestors alive. But today, it can keep us stuck in jobs, habits, or mindsets that no longer serve us.

In fact, my brain is, at this second, yelling at me to stop writing this because it's a cringy waste of time. It's telling me to go back and do more “productive” things instead. But don’t worry, I’m ignoring it.

This internal resistance is why so many well-intentioned resolutions, pivots, or bold goals quietly stall out. It’s not a lack of discipline. It’s biology.

The good news is, once you understand the science, you can work with your brain instead of against it.

Here’s what’s going on neurologically and how to respond:

• Resistance is a safety mechanism, not a flaw
  The amygdala, part of the brain’s fear center, interprets uncertainty as potential danger. When you consider a big change, such as quitting, launching, or shifting identity, it flags that as a risk.
  
  Neuroscience even shows that uncertainty activates the same brain areas as physical pain. That’s why change can feel physically uncomfortable, even when it’s the right move.
  

• Habits are protected by your brain's “efficiency filter.”
  Your basal ganglia favors automation. It prioritizes routines to conserve energy and will often override the logical part of your brain (the prefrontal cortex) to keep you in your comfort zone.
  
  So when you try to build a new habit like eating differently, waking up earlier, or thinking in new ways, your brain pushes back. Not because it's bad, but because it's trying to protect efficiency. This is called a neural efficiency loop.

• Motivation doesn't come first. It often follows action
  One of the most surprising findings in behavioral science is that action fuels motivation more reliably than the other way around.
  
  In a classic study on behavior change, researchers found that simply taking a small step, even if you don’t feel ready, increased belief in your ability to follow through. Think of it as momentum over mindset.

Not ready to start your own business? Share your idea with one person (this is how I got started!)

Not ready to run a 5k? Go jog for 10 minutes (this is how I went from being a coach potato to a Spartan half-marathon runner).

3 Strategies That Work With Your Brain

1. Shrink the change
If you want to outsmart fear, make the first step so small your brain doesn’t perceive it as a threat.

Instead of “change jobs,” I told myself, “Draft one email to a mentor.” That felt doable and opened the door to motion.

Ask yourself: What’s the tiniest next step I can take that still moves me forward?

2. Visualize the new normal, not just the outcome
It’s easy to fantasize about the result: more freedom, better health, a new role. But your brain needs repetition to believe in a new identity.

One research-backed approach is episodic future thinking: imagining vivid, detailed scenes from your future daily life. Not just the trophy, but the Tuesday.

For me, when starting Nourish, that meant imagining myself at a coworking space, answering customer emails.

Try this: Visualize yourself living your new routine, down to the sensory details. That helps your brain encode the change as familiar.

3. Celebrate small wins to rewire reward pathways
When you reward progress, no matter how small, you strengthen the dopamine loop that reinforces action.

That’s why crossing off a list item or sharing a win with a friend matters more than we think.

Over time, your brain starts to associate change with pleasure instead of discomfort.

Launching Nourish felt massive at the start.

But what got me through wasn’t a surge of courage. It was a series of tiny, unglamorous steps.

DMing someone. Making a test order. Saying “I’m building something” out loud, even when I wasn’t sure yet.

Change isn’t about being fearless. It’s about understanding your fear and moving forward anyway.

Your brain will resist. But it’s not the enemy; it’s trying to protect you. With the right tools, you can show it that what’s ahead isn’t dangerous. It’s just unfamiliar.

And maybe, just maybe, it’s exactly what you were built for.
