Memory Techniques: How I Discovered the Secret of the Ancient Greeks

Why I Always Forget Things (and How That’s Changing)

I had a problem. Actually, I thought I had a genetic issue or something like that.

You know that feeling of studying all afternoon, understanding the content perfectly, feeling confident… and two days later remembering absolutely nothing? That was exactly what happened to me. No matter how much time I dedicated, how much I underlined, or how many times I reread—the information simply evaporated from my head.

In daily life, this manifested in almost comical (if not frustrating) ways:

• I’d go to the market without a list and come back with half the wrong things.
• I’d meet someone at a party and forget their name while I was still talking to them.
• I’d study for college exams and have to start from scratch every time because it was as if I had never seen the material before.
• I’d watch entire video lessons and, when it came time to apply them, I couldn’t remember the main concepts.

The worst part? I had convinced myself that “I simply don’t have a good memory.” As if it were a fixed, immutable personality trait. As if some people were born with the gift of memory and others (me) were condemned to forget everything forever.

Spoiler: I was completely wrong.

The Greeks’ Trick: The Memory Palace I Didn’t Know

Everything changed when I stumbled upon a YouTube video about ancient memory techniques. That’s when I met Simonides of Ceos—a Greek poet who lived around 500 B.C. and who, unintentionally, invented one of the most powerful memory techniques in history.

The story is a bit insane, but it’s worth telling:

Simonides was at a banquet, reciting poems for the guests. In the middle of the party, he was called outside the hall. While he was outside, the roof of the place collapsed and killed everyone inside. The bodies were so mangled that no one could identify who was who.

That’s when Simonides realized something extraordinary: he could remember exactly where each person was sitting. He closed his eyes, mentally reconstructed the layout of the hall, and was able to identify each victim by their position at the table.

This gave rise to a revolutionary idea: our minds remember places and visual images much better than dry lists of information.

Think with me—you can perfectly describe the way from your house to the nearest market, right? You can remember where each room in your house is, the color of the walls, where each piece of furniture is located. But try to remember a list of 20 random words you read 5 minutes ago… much harder, right?

The ancient Greeks (and later the Romans, and then everyone who took memorization seriously) turned this observation into a technique: the Method of Loci, better known as the Memory Palace.

The idea is absurdly simple and yet brilliant: you take information you need to memorize and transform it into vivid and bizarre images, placing them in specific locations of a place you know very well.

How the Memory Palace Works

After researching the subject extensively, I realized that the human brain is a bit strange in its preferences. It loves visual stories, familiar places, and unusual things. But it hates abstract lists, loose numbers, and disconnected concepts.

The Memory Palace works because it plays to these brain preferences:

1. Choose a Familiar Place

It could be your house, your bedroom, the path you take every day to college, your grandmother’s house—any place you know perfectly. The secret is that you need to be able to “walk” through this place mentally without effort.

2. Define Reference Points (Loci)

Within this place, you mark specific points. In your house, for example: the front door, the living room sofa, the refrigerator, your bed, the bathroom mirror… These will be the “hooks” where you will hang the information.

3. Transform Information into Bizarre Images

This is where the magic happens. You take each item you need to memorize and transform it into an absurd, exaggerated, funny, or grotesque visual image. The crazier, the better.

For example: need to remember that “mitochondria is the powerhouse of the cell”?

• I imagine my front door (first loci) with a giant, hairy mitochondria that is literally glowing and making the sound of a power plant, with lightning bolts coming out of it.

Need to remember that “Napoleon was exiled to Saint Helena in 1815”?

• I visualize my sofa (second loci) with a tiny Napoleon sitting on it, crying, while holding a sign that says “SAINT HELENA” and wearing a hat shaped like the number “1815”.

4. Connect the Images to the Path

The final part is to mentally “walk” through your palace in the right order. You enter through the door (electric mitochondria), pass by the sofa (crying Napoleon), go to the refrigerator (next image), and so on.

Why does this work so well?

The brain is doing several things at once:

• Associating new information with something it already knows deeply (your house).
• Creating emotional connections through absurd images (emotion = stronger memory).
• Using spatial memory, which is evolutionarily very old and powerful.
• Transforming abstract concepts into concrete sensory experiences.

It’s as if you’re tricking your brain into treating a boring list as if it were a lived experience.

Testing in Practice (What I Did and What I Noticed)

Theory is nice, but I needed to test if this actually worked or if it was just another one of those “productivity tricks” that are useless.

My First Test: Shopping List

I started simple. I needed to buy: milk, bread, apples, laundry detergent, toilet paper, chicken, lettuce, and beer.

My palace? My own bedroom (because I practically live here).

• Bedroom door: a river of milk gushing under the door, wetting my foot.
• Study desk: a giant bread sitting in the chair, wearing my headphones.
• Bed: completely covered by bright red apples, as if they were sheets.
• Wardrobe: exploding laundry detergent like snow, making everything white.
• Bookshelf: unrolled toilet paper wrapping all the books like mummies.
• Ceiling fan: a whole chicken hanging from the blades, spinning.
• Window: lettuce growing around the edges like climbing plants.
• Trash can: full to the brim with beer bottles.

The result? I went to the market without a list and remembered everything. For the first time in my life.

What Worked Right Away:

• Absurd images are better than normal images: the more bizarre, the easier to remember.
• Movement helps a lot: still things are easier to forget than things doing something.
• Emotion intensifies: if the image makes you laugh, feel disgusted, or surprised, you’ll remember it better.
• Order matters: always following the same mental path keeps everything organized.

Mistakes I Made (and You Can Avoid):

• Not exaggerating enough: at first, I created images that were too “well-behaved” and they didn’t stick.
• Trying to memorize too much at once: starting with 5-8 items is ideal, then you can increase.
• Not reviewing the palace: creating the images and never “walking” through the palace again makes you forget.
• Using places that are too similar: if all the rooms are white and empty, it’s hard to differentiate.

Before/After Comparison:

Before the Memory Palace:

• List of 10 random items: remembered 3-4 after a few minutes.
• Studied content: forgot 70-80% in 2-3 days.
• People’s names: forgot instantly.

After 2 weeks of practice:

• List of 20 items: I can remember perfectly for days.
• Studied content: I retain at least 60-70% for weeks.
• Names: by creating funny mental images, I remember instantly.

It’s not magic—you need to practice. But the result is totally worth it.

Other Techniques I Saw (to Complement the Palace)

While I was researching the Memory Palace, I discovered that there are several other memory techniques that work great together. Some are variations of the same idea, others complement in different ways.

Method of Loci (It’s Literally the Same Thing)

“Loci” comes from Latin and means “places.” It’s just the more formal and academic name for the Memory Palace. When you see someone talking about the “method of loci,” you can relax—it’s exactly the technique I explained above.

Chunking (Grouping into Smaller Pieces)

I was already using this technique without knowing it. It’s basically breaking large pieces of information into smaller, more manageable groups.

For example:

• Phone number: instead of remembering “11987654321”, you remember “(11) 98765-4321”—three chunks.
• Studying history: instead of memorizing 50 dates, group them into periods (Colonial Era, Imperial Era, Republic).
• New vocabulary: group words by theme or similar sound.

How I use it with the Palace: when I have a lot of information, I do chunking first to reduce the number of mental images I need to create. It works perfectly.

Spaced Repetition (Reviewing at the Right Time)

This one is fundamental and revolutionized the way I study.

The idea: it’s no use reviewing 10 times on the same day and never returning to the subject. The secret is to review at the exact moments when your brain is about to forget.

The schedule I use (based on Ebbinghaus’s Forgetting Curve):

• 1st review: 1 day later
• 2nd review: 3 days later
• 3rd review: 7 days later
• 4th review: 15 days later
• 5th review: 30 days later

After that, the information has usually entered long-term memory.

How I use it with the Palace: I create the palace on the day I study the content, and during reviews, I simply “walk” through the palace mentally again. Each review becomes faster and more automatic.

Mnemonics (Acronyms and Crazy Phrases)

These are those tricks like “My Very Educated Mother Just Served Us Noodles” to remember the order of the planets (Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune).

How I use it with the Palace: sometimes I combine them—I create an absurd mental image of the mnemonic phrase and place it in the palace. It’s mnemonic + palace = superpower.

Which Ones Will I Use Going Forward?

Note to myself (and to you):

The Perfect Combination I Discovered:

1. Memory Palace as the main base (for everything that needs to be organized in order).
2. Chunking before creating the palace (to reduce complexity).
3. Spaced Repetition to keep it alive (reviewing at the right intervals).
4. Mnemonics to complement when it makes sense (names, specific lists).

This is the combination I’m using now in my studies. You don’t need to use everything at once—start with the Palace, master it, and add the others as you feel the need.

What Really Changed (and What’s Next)

After weeks of testing these techniques, I can honestly say: my relationship with learning has changed.

It’s not that I became a genius or developed a magical photographic memory. But I understood something fundamental: memory is not a talent you have or don’t have—it’s a skill you train.

The coolest part? The more I practice, the faster it gets to create mental palaces. In the beginning, it took 10-15 minutes to set up a palace with 10 items. Today I can do it in 2-3 minutes.

And the best of all: it works for anything. Shopping lists, exam content, people’s names, language vocabulary, math formulas, historical dates… literally anything you need to remember.

But there’s a catch: knowing the technique is just the beginning. Applying it in daily life, in real studies, in practical situations—that requires a bit more strategy and organization.

That’s why, in the next post, I’ll show exactly how I’m applying the Memory Palace to my studies—with practical examples, mistakes I made, adjustments I made, and a step-by-step guide on how you can start today.

Until then, try creating your first mental palace. Choose a place you know, think of 5 things you need to remember, and transform each one into an absurd image placed at a specific point in that place.

Then tell me if it worked. Because for me it worked—and it completely changed the way I learn.
