When I started designing things, I wanted as many options as possible. More colors, more typefaces, more screen sizes to design for, more components in the library. I thought that freedom was the precondition for good work. More choices meant more chances to find the right one.
I was wrong about this in a specific way. The problem with unlimited options is not that they produce bad output — sometimes they produce fine output. The problem is that they make every decision feel arbitrary. When you can use any of twelve typefaces, you have to justify whichever one you pick. When you only have two, the question answers itself. Constraint is not a limitation on creativity. It is a structure that holds creative energy in place long enough for it to do something.
A haiku is seventeen syllables not because seventeen syllables is the correct size for a thought, but because the limit forces a kind of precision that longer form lets you avoid. You cannot hide in a haiku. You cannot hedge. The constraint makes honesty the only option. I think about this when I am writing a component with too many props, or designing a screen with too many possible states. The proliferation of options is often a sign that the problem has not been understood yet.
The best brief I ever worked from was one sentence. It was also the most constraining. I spent more time on that project than any other, and I am more certain about every decision in it. I do not think that is a coincidence.
