Mies van der Rohe's statement, less is more, is a basic tenet of modernism. It was a rejection of the decadent 19th-century eclectic Victorian excess. After the terrors of World War I, designers rejected the decorated and regional aesthetic adopted by the upper classes. To avoid another war, they sought to find a universal form of design. It would be based on pure geometry and mathematics. These had no political associations. When all people adopted these simple and pure forms, peace would flourish.
But people are people. We like things. Nobody wants to live in a cold concrete cell with a mattress and steel chair. But, after the roller coaster of last week's election, I'm up for the simpler approach.
Restraint is the hardest skill to master as a designer. To stop feels lazy, or unfinished. But the results of saying, "I'm done." can lead to simple and clear harmony. To continue can slowly move a solution from sublime minimalism to ordinary. With the right words, one black and white line of text on a page has power. Add an image, second color, and border, and it's nice. Only nice.
Just say no. Stop, and let something be what it is and no more. Do nothing.
