Less, but Better
Dieter Rams said it in three words: less, but better. Not less for the sake of less. Less in service of better. Every removal should make what remains more true.
Most design fails not from what is missing, but from what should never have been added. The extra button, the clever animation, the third typeface. Each one seemed like a good idea alone. Together they are noise. The designer's real job is to be the person in the room willing to say: take it out.
This is harder than it sounds, because removal feels like loss. You made the thing. You liked the thing. But taste is not about what you can add. It is about what you can let go of. The white space is not empty. It is doing work.
Look at anything you love, a room, a song, a meal, a sentence, and you will find the same pattern. Someone decided what mattered and had the courage to remove the rest. Less, but better is not a style. It is a discipline. Practice it daily.
