Everyone thinks they know Leonardo da Vinci. He’s the guy who painted that lady with the weird smile and sketched a helicopter five hundred years before anyone could actually fly. But honestly, if you look at his actual life, the "Renaissance Man" trope feels kinda reductive. He wasn't just some polished genius sitting in a studio. Leonardo was a mess of unfinished projects, weird obsessions with horse anatomy, and a guy who spent way too much time wondering why the sky is blue. He was human. Frustratingly human, actually.
Most people see him as a symbol of perfection. He wasn't. He was a chronic procrastinator. He drove his patrons crazy because he’d start a masterpiece and then get distracted by how a dragonfly’s wings move. If you’ve ever started a hobby and abandoned it three weeks later, you’ve basically got the Da Vinci spirit.
What Most People Get Wrong About Leonardo da Vinci
We tend to deify him. We think every stroke of his brush was a calculated move toward immortality. In reality, Leonardo da Vinci was often just trying to figure out how stuff worked so he could make his paintings look "right." He didn't study optics because he wanted to be a scientist; he studied optics because he wanted to understand how light hits a human cheekbone.
There's this idea that he was a lone wolf, a mysterious hermit. Not true. He was famously handsome, loved fine clothes—specifically rose-colored tunics—and was a vegetarian who would buy caged birds just to let them go. He was the life of the party in Milan and Florence. People liked him. He played the lyre. He sang. He was a socialite who happened to have the most terrifyingly active brain in human history.

The Myth of the "Secret Code"
Thanks to pop culture, everyone looks for hidden messages in his work. Did he hide a map to the Holy Grail in the The Last Supper? Probably not. The real "secrets" in his work are technical. He used a technique called sfumato, which is basically blurring the edges so things look smoky and realistic. It’s why the Mona Lisa feels like she’s breathing. There’s no hard outline. Life doesn't have outlines. Leonardo figured that out by dissecting over 30 corpses—which, by the way, was totally illegal and incredibly gross back then. He did it anyway. He wanted to see the muscles.
Why the Notebooks are Actually More Important Than the Art
If you only look at his paintings, you’re seeing maybe 10% of the man. The real Leonardo da Vinci lives in his notebooks. There are thousands of pages. They are written in mirror script—backward—mostly because he was left-handed and didn't want to smudge the ink, not because he was trying to hide his grocery list from the Pope.
In these pages, you see his brain vibrating. He’ll have a sketch of a human heart right next to a design for a giant crossbow. He’d write notes to himself like "describe the tongue of the woodpecker." Who does that? Someone who is deeply, pathologically curious.
The Engineering That Never Was
He designed tanks. He designed scuba gear. He designed a "mechanical lion" that could walk and open its chest to reveal lilies. Most of these things were never built. Some wouldn't have worked. His tank design had a flaw where the wheels turned against each other—some historians think he did that on purpose because he hated war and didn't want people actually using his weapons.
He was a dreamer. But a dreamer with a protractor.
- The Flying Machine: He spent decades watching birds. He realized humans don't have the chest strength to flap wings. He eventually pivoted to gliders.
- The Water Master: He was obsessed with flow. He designed canals for the city of Milan that are still referenced today.
- Anatomy: His drawings of the fetus in the womb were so accurate they weren't surpassed for centuries. He did this without MRI machines. He just had a knife and a very strong stomach.
The Struggle of the Perfectionist
The biggest tragedy of Leonardo da Vinci is how much he didn't finish. The Adoration of the Magi? Unfinished. The Battle of Anghiari? Lost and ruined. He spent years on a giant bronze horse for the Duke of Milan, only for the French to invade and use the clay model for target practice.
He was a perfectionist to a fault. He’d spend days on a single detail and then abandon the whole thing because he lost interest or felt he couldn't achieve the impossible standard in his head. This is why we only have about 15 to 20 paintings that are definitely his. That's it. For a guy who lived to be 67, that’s a tiny output. But those few works changed the world.
The Mona Lisa Obsession
He didn't even give the Mona Lisa to the person who commissioned it. He kept it. He hauled that piece of wood across the Alps on a mule when he moved to France. He kept working on it until he died. He was never done with it. That’s the secret. It’s not a code; it’s a guy who couldn't stop tweaking his favorite project.

Was He Really a Scientist?
By modern standards, he was more of a "natural philosopher." He didn't always follow the scientific method we use today—hypothesize, test, repeat. He observed. He was the king of "look at that."
He realized the earth was older than the Bible said because he found sea fossils on top of mountains. He understood that the sun doesn't move, long before Copernicus made it a big deal. He was a man out of time, but he was also very much a product of the Renaissance—a time when you could be an artist and an engineer and a musician all at once without people telling you to "stay in your lane."
How to Think Like Leonardo Today
You don’t have to be a genius to use his methods. Leonardo da Vinci relied on three things that anyone can do: observation, curiosity, and cross-pollination.
He didn't keep his interests in silos. He used his knowledge of water flow to understand how blood moves through heart valves. He used his knowledge of light to make his buildings look better. He was the ultimate "T-shaped" person.
Actionable Steps to Channel Your Inner Da Vinci
If you want to actually apply his mindset to your life, forget about the painting part for a second. Focus on the brain part.
- Carry a notebook everywhere. Don't use your phone. Draw things. Even if you suck at drawing. Forcing your hand to replicate what your eye sees changes how you perceive the world.
- Ask "Why" about boring stuff. Why do bubbles stay round? Why do leaves change color? Leonardo asked these questions and wrote them down.
- Connect the dots. If you work in tech, read a book on biology. If you’re a teacher, look at how architects organize space. The best ideas happen at the intersections.
- Accept the "Unfinished." Not every project needs to be a masterpiece. Leonardo’s notebooks are full of failures and half-baked ideas. That’s where the growth happens.
The Reality of the Legend
Ultimately, Leonardo da Vinci represents the limit of what one human can know. He tried to learn everything. Everything. He failed, of course, because nobody can know everything. But the attempt is what made him Leonardo.

He died in France, allegedly in the arms of King Francis I (though that’s probably a bit of a legend). Even on his deathbed, he supposedly apologized to God and man for "leaving so much undone."
That’s the takeaway. Even the greatest mind in history felt like he ran out of time. So, stop worrying about being perfect. Just start observing. Look at the world a little closer today. Notice the way the light hits a glass of water or the way a tree branches out. That’s where the genius starts. It’s not in the paint; it’s in the looking.

Practical Next Steps:
Start a "Commonplace Book." This is what the greats did. Dedicate one physical notebook to everything—sketches, quotes, math problems, grocery lists. Don't categorize it. Let the chaos of your interests live in one place. Over time, you’ll start seeing patterns between your job and your hobbies that you never noticed before. This is the exact method Leonardo used to bridge the gap between art and science.
