You've probably heard it a thousand times when you're stressed out. Someone—usually a well-meaning friend or a yoga instructor—tells you to just let it go just let it be. It sounds like the easiest thing in the world, right? Like just opening your hand and dropping a hot coal. But if you’ve ever actually tried to do it while your heart is racing or you’re replaying a three-year-old argument in your head at 2:00 AM, you know it feels more like trying to stop a freight train with a toothpick.
We live in a culture obsessed with "fixing." We fix our cars, our diets, our careers, and our partners. We treat our emotions like software bugs that need a patch. But the actual psychology behind letting things be isn't about fixing anything at all. It’s about a radical, slightly uncomfortable shift in how we relate to the stuff we can't control.
The Science of the "Stuck" Brain
Why can't we just flip a switch? Honestly, your brain is wired to do the exact opposite.
Neuroscientists often talk about the Default Mode Network (DMN). This is the part of your brain that kicks in when you aren't focused on a specific task. It’s the daydreaming center, the "me" center. When we are ruminating on a mistake or a breakup, the DMN goes into overdrive. It’s trying to solve a problem that might not have a solution.
Research from Harvard University, specifically a famous study by Daniel Wegner on "ironic process theory," shows that trying to suppress a thought—to "let it go" by force—actually makes it stickier. If I tell you right now, do not think about a pink elephant, what are you looking at in your mind? Exactly. The more you tell your brain to stop obsessing over that weird comment your boss made, the more your brain flags that comment as "Critically Important: Do Not Forget."
Radical Acceptance vs. Giving Up
There is a huge misconception that to just let it go just let it be means you’re being a doormat. It’s not.
In clinical psychology, particularly in Dialectical Behavior Therapy (DBT), there’s a concept called Radical Acceptance. Marsha Linehan, the creator of DBT, argues that suffering happens when we refuse to accept reality. Acceptance doesn't mean you like what’s happening. It doesn't mean you agree with it. It just means you stop fighting the fact that it is happening.
Think about being stuck in a massive traffic jam when you're already late.
You can honk.
You can scream.
You can feel your blood pressure spike until your ears ring.
Does the traffic move? No.
The "let it be" approach is acknowledging: "I am in traffic. I am late. This sucks." By stopping the internal war against the reality of the traffic, you save the energy you'd otherwise burn on useless rage.
Why We Cling to the Hurt
It’s kinda weird when you think about it. Why do we hold onto things that make us miserable?
Usually, it’s because the pain feels like a form of protection. If we stay angry at someone who hurt us, we feel like we’re keeping our guard up so it doesn't happen again. If we let go of the anger, we feel vulnerable. Or maybe we feel like our anger is a way of seeking justice. We think, If I let this go, it means what they did was okay. But here’s the reality: your resentment isn't a weapon against the other person. It’s a weight you’re carrying.

Dr. Fred Luskin, who heads the Stanford Forgiveness Projects, has spent years studying this. His work shows that holding onto grudges creates a physical "stress response" in the body. We’re talking cortisol, adrenaline—the whole cocktail. When you finally learn to just let it go just let it be, you aren’t doing the other person a favor. You’re literally just letting your own nervous system catch a break.
The Myth of Closure
We’re obsessed with closure. We want the apology. We want the "why."
But waiting for someone else to give you closure is like waiting for a flight at a bus station. It's not coming. Real "letting go" happens when you realize that you can move forward without ever getting the explanation you think you need. You decide that your peace of mind is more valuable than being "right" or being "understood" by someone who isn't interested in understanding you.
Practical Ways to Actually Do It
So, how do you actually practice this without sounding like a Hallmark card? It’s a skill, not a personality trait. You have to train your brain like a muscle.
The 90-Second Rule.
Neuroanatomist Dr. Jill Bolte Taylor suggests that the chemical process of an emotion lasts about 90 seconds. When you feel a surge of anger or anxiety, that’s just a physiological wave. If you can just sit with it for a minute and a half without "feeding" the emotion with new thoughts (like I can't believe he said that!), the wave will naturally crest and subside.Change Your Language.
Instead of saying "I am angry," try saying "I am noticing a feeling of anger." It sounds small, but it creates a gap. You aren't the emotion; you’re the person observing it.The "Wait and See" Method.
Sometimes, we try to "let go" of a future worry. What if I lose my job? What if this relationship fails? Just let it be means admitting you don't know the ending yet. You’re living in the middle of the book. You can't solve page 200 when you're only on page 50.Physical Release.
Sometimes the mind is too loud to listen to logic. Shake your arms. Go for a run. Scream into a pillow. Your body stores tension, and sometimes you have to let the physical energy out before the mental loop stops.
The Role of Mindfulness (Without the Fluff)
Mindfulness has become a buzzword, but at its core, it’s just the practice of "being" rather than "doing."
When you’re trying to just let it go just let it be, you’re moving from a state of striving to a state of witnessing. Most of our lives are spent striving. We want more money, better skin, a cleaner house. We’re always trying to bridge the gap between where we are and where we think we should be.
"Letting it be" is the act of closing that gap. It’s saying, "For this moment, right now, this is enough."
Even if "this" is messy.
Even if "this" is sad.
There’s a famous story about a monk who was asked how he found peace. He said, "When I sit, I sit. When I eat, I eat." It sounds simple, but most of us are eating while thinking about work, and working while thinking about dinner. We are never where we actually are.
Real-World Examples of Letting Go
Look at professional athletes. If a golfer misses a crucial putt, they have about ten seconds to just let it go just let it be before the next shot. If they carry the frustration of the miss into the next swing, they’ll miss that one too. They call it "the short memory."
Elite performers in any field—surgeons, pilots, musicians—all have this. They don't have the luxury of rumination. They acknowledge the error and immediately return to the present task.
Or look at nature. A tree doesn't hold onto its leaves in the autumn because it’s afraid it won't get new ones in the spring. It lets them go because it has to. It’s a part of a cycle. We are the only species that tries to keep our "dead leaves" attached to us for years, wondering why we feel so heavy.
The Limitations of the "Let it Go" Philosophy
Let’s be real for a second. There are things you shouldn't just "let be."
Injustice.
Abuse.
Dangerous situations.

There is a fine line between spiritual peace and passive avoidance. If someone is mistreating you, "letting it be" isn't the answer—boundaries are. The trick is knowing the difference between a situation that requires action and a situation that requires acceptance.
If you can change it, change it.
If you can't change it, and it's hurting you, walk away.
If you can't walk away and you can't change it, that is where the work of letting go begins.
Actionable Steps to Shift Your Mindset
If you're feeling stuck right now, don't try to force a massive life transformation. Start small.
- Identify the "Hook": What is the specific thought you're chewing on? Write it down. Often, seeing it on paper makes it look smaller than it feels in your head.
- Set a "Worry Window": Give yourself 15 minutes at 4:00 PM to obsess, cry, and be furious. When the timer goes off, you're done for the day. This gives your brain the "solve" time it craves without letting the mood bleed into your whole life.
- Focus on the Senses: When the spiral starts, name five things you can see, four things you can touch, three things you can hear. It grounds you in the "now" where the "letting be" actually happens.
- Accept the Non-Acceptance: Sometimes you can't let go. That’s okay too. Just let the fact that you're struggling be. Stop judging yourself for not being "zen" enough.
Learning to just let it go just let it be isn't a destination you reach. It’s a practice you'll probably have to do every single morning for the rest of your life. And that's fine. The goal isn't to never feel bothered again; it's to get better at noticing when you're holding on too tight and having the courage to relax your grip.
Start by taking one deep breath. Don't try to change how you feel. Just notice the breath. That’s the first step to letting it be.
Next Steps for Mastery:
- Audit your "Musts": Spend the next 24 hours noticing how often you use the word "should" or "must" regarding things you cannot control.
- Practice the 90-Second Rule: The next time someone cuts you off in traffic or sends a stinging email, set a timer. Observe the physical sensation of the annoyance without adding a "story" to it.
- Physical De-cluttering: Often, our external environment mirrors our internal state. Choose one small area—a drawer or a desktop—and clear it out to physically signal to your brain that it is okay to release what is no longer serving a purpose.
