“Simplicity is the ultimate sophistication,” wrote Leonardo Da Vinci. He would paint over work that didn’t meet up with his expectations.
Simplicity is the reduction of complexity. It subtracts the gray space in the middle and renders it black and white.
Simplicity comes from revision
Simplicity retains the essence and deletes the rest. Take a look at the sequence of Picasso’s drawing of a bull. He pairs down the bull from full detail down to its fundamental shape.
Once we remove the excess, we can retain what’s essential. But the final result appears intuitive because all the explaining was done in its reduction.
