You’re standing in the kitchen, staring at a pile of mail, and suddenly it hits you. It’s already October. Or maybe it’s Tuesday, but you could’ve sworn it was just Sunday morning. That weird, slightly sinking feeling in your gut isn't just you getting older, although that’s part of it. We all joke about it on social media—how 2020 felt like a decade and 2024 disappeared in a weekend—but the science behind why time is flying by so fast is actually pretty fascinating, and honestly, a little bit terrifying if you don’t know how to slow it down.
Time isn't speeding up. The Earth is still spinning at the same rate. Your watch isn't broken. But your brain? Your brain is a master of compression. It takes the messy, beautiful, boring reality of your life and zips it up into a tiny file that makes the last five years look like a highlight reel that lasts thirty seconds.
The Proportional Theory: Why Five Minutes Isn't Just Five Minutes
There’s this famous idea often attributed to Paul Janet, a 19th-century French philosopher. He argued that we perceive time through the lens of how much life we’ve already lived. Think about it. When you are 5 years old, one year represents a massive 20% of your entire existence. That summer break felt like an eternity because, relative to your total memory bank, it was.
But once you hit 50?
That same year is only 2% of your life. It’s a drop in the bucket. To a child, the wait for Christmas is an agonizing marathon; to an adult, Christmas seems to happen every three weeks. This proportional shrinking of time creates a psychological treadmill where the faster you run, the shorter the track becomes. It’s a mathematical trap.
The "First-Time" Effect and Why Routine Is the Enemy
Have you ever noticed that the drive to a new vacation spot feels like it takes five hours, but the drive home feels like it takes twenty minutes? That is the Oddball Effect in action.
Our brains are designed to prioritize new information. Evolutionarily speaking, if you see a new type of berry or a predator you've never encountered, your brain drops everything to record every single detail. It goes into "high-definition" recording mode. This takes up a lot of "space" in your memory. When you look back on that period, your brain sees a wealth of data, and you perceive that time as having lasted a long time.
Routine kills that.

When you do the same thing every day—commute, desk, lunch, commute, Netflix, sleep—your brain stops recording. It doesn't need to. It knows what your office looks like. It knows the taste of your morning coffee. To save energy, it basically hits "copy-paste" on your memories. When you look back at a month of routine, your brain sees one single "day" of data repeated 30 times. It collapses. Suddenly, you're wondering where the month went. The reality is that time is flying by so fast because you aren't giving your brain anything new to anchor it down.
The Holiday Paradox
Psychologist Claudia Hammond, author of Time Warped, talks about the "Holiday Paradox." While you’re on a trip, if things are busy and exciting, time might feel like it’s rushing by in the moment. You're having fun. You aren't checking your watch. But as soon as you get home and look back, that week feels huge. It feels like you were gone for a month because of the sheer density of new memories.
Contrast that with a boring week at work. In the moment, every hour drags. You're staring at the clock. It’s slow. But on Sunday night, you look back and the week is a total blur. It’s gone. This is the great irony of human perception: the more "boring" your life is, the faster it seems to pass in retrospect.
Dopamine, Stress, and the Biological Clock
It’s not just about memory; it’s about biology. Our internal pacemakers are influenced by neurotransmitters, specifically dopamine. Studies have shown that when we are excited or stimulated, our internal "pulse" speeds up. If your internal clock is running faster than the actual clock, the world seems to slow down.
Then there's the stress factor.
High cortisol levels—the stuff that floods your system when you're burnt out or rushing—actually messes with your temporal processing. When you’re constantly "on," your brain is trying to process information at a frantic pace. This creates a disconnect. You feel like you're racing against the sun every single day.
We also have to talk about the "Reminiscence Bump." If you ask a 70-year-old to tell you their life story, they usually don't spend much time talking about their 40s or 50s. They talk about their late teens and 20s. Why? Because that’s when everything was new. First job. First love. Moving out. Buying a house. The brain was "on" during those years. After 30, for many people, the "firsts" start to dry up, and the mental clock starts its relentless acceleration.
Technology is Shaving Seconds Off Your Life
We can't ignore the digital elephant in the room. Our phones have fundamentally changed how we experience the passage of time.
Think about "micro-moments." In the past, if you were waiting for a bus, you’d just... sit there. You’d look at the trees. You’d people-watch. You’d be bored. That boredom was a signal to your brain to inhabit the present moment. Now, we fill every three-second gap with a scroll through a feed. We are constantly consuming "snackable" content—15-second videos, 280-character thoughts.
This constant switching of attention fragments our perception. It’s called "Time Compression." By jumping from a news story in Ukraine to a cat video to a work email in the span of sixty seconds, we are preventing our brains from forming a cohesive "anchor" in time. We are living in a permanent, shallow "now" that leaves no footprint in our long-term memory.
How to Put the Brakes on Your Life
If you feel like time is flying by so fast, you don't have to just accept it. You can't stop the earth from turning, but you can change how your brain encodes the experience. It requires a conscious effort to break the "copy-paste" cycle.
Seek Novelty (Even Small Stuff)
You don’t need to skydive every weekend. Just drive a different way to work. Eat at a restaurant you’ve never tried. Walk on the other side of the street. These small injections of "newness" force your brain to pay attention and record new data.
The Power of the "Weekly Reset"
On Sundays, instead of just dreading Monday, try to write down three things that happened that week that were unique. If you can't think of three, that’s a sign your routine is too tight. By reflecting on the week, you're essentially "thickening" the memory and making it harder for your brain to compress it.
Monotasking over Multitasking
Multitasking is a lie. Your brain just switches back and forth really fast, which increases stress and makes time feel frantic. Try to do one thing at a time. If you're drinking coffee, just drink the coffee. Don't scroll. Don't check the news. Just be there. It feels weirdly long when you do it, which is exactly the point.

Practice "Purposeful Boredom"
Next time you're in line at the grocery store, leave your phone in your pocket. It will feel like an eternity. That’s good. That’s you reclaiming those minutes. You're actually experiencing the time instead of deleting it with a screen.
Taking Action to Reclaim Your Years
Understanding that your perception of time is a flexible, biological construct is the first step. You aren't a victim of the calendar. You are the architect of your memories. If you want the next ten years to feel like they actually lasted a decade, you have to feed your brain more than just routine and digital noise.
- Audit your routine: Identify three things you do on autopilot every day and change one of them tomorrow.
- Create "Memory Anchors": Plan one "mini-adventure" every month. It doesn't have to be expensive—a hike in a new park, a museum visit, or even a weird DIY project.
- Document the mundane: Take photos of things that aren't "Instagrammable." Your messy desk, the way the light hits your kitchen in the afternoon. These visual cues help your brain reconstruct the "empty" spaces of your life.
- Set "No-Phone" zones: Specifically during transitions (commutes, waiting areas). Force yourself to inhabit the "gap" time.
Life is short, but it doesn't have to feel like a blur. By being intentional about what you give your attention to, you can stretch the minutes and make sure that when you look back, you see a life that was actually lived, not just a series of compressed files and forgotten Tuesdays.
