Leonardo da Vinci started his solo career with two failures. He abandoned his first two solo commissions. Instead, he switched focus and tried to market himself to the Duke of Milan as musician and engineer, only briefly mentioning his painting ability.

Leonardo da Vinci spent 3 years painting The Last Supper for a monastery. After complaints of delays, Leonardo claimed that he was "still searching" for the perfect model for the face of Judas. An act of Renaissance brilliance or a witty ADHD excuse?

What about all of Leonardo da Vinci's inventions? Didn't he invent the helicopter? He created extensive notes and sketches, but never published any of it. Leonardo da Vinci's engineering brilliance was never put to use because it was all hidden away in his personal notebooks.

Leonardo da Vinci famously dissected corpses to analyze & sketch the human body. He was working with a professor named Marcantonio Della Torre to create a "treatise on anatomy". Della Torre died from The Plague before they finished. Leonardo lost interest & it was abandoned.

But what about "The Vitruvian Man"? Wasn't that published? It was just a sketch found in one of his notebooks. It was never published.pic.twitter.com/hxZuudBcdO

Leonardo da Vinci made incredible discoveries about human anatomy, but none of this knowledge was put to use. It was only *500* years after his death, in 1968, that his anatomical notebooks were finally found & published.

Leonardo da Vinci wrote 13,000 pages worth of notes, drawings, art, and plans. They are totally out of order with random switches in topics, categories, and focus. Like his anatomical work, none of this was published or recognized for hundreds of years.

In summary, Leonardo da Vinci was a man who rapidly switched from one hyperfocus to another. He rarely completed any of his grandiose projects and even considered his life a failure. He was a genius artist & inventor who suffered from obvious ADHD symptoms.

To me it's clear his grandiose ideas, genius inventions, difficulties with sleep, insatiable curiosity, and mercurial lifestyle, were moments of extreme ADHD hyperfocus combined with his extreme human intelligence & artistic talent.

Reading his biography made me sad. He lived in a time where his inability to complete projects was labeled as "lazy" or some form for moral failure. By all accounts he was loved and admired by those around him, but he couldn't stop getting in his own way. "He offended God"

I wonder how much more Leonardo da Vinci could have accomplished if he understood his ADHD symptoms and used his own genius to devise a strategy around it. His anatomical work alone would have made him world famous 10 times over. More quotes about him:
