Brilliant and simple, the way it should be, I added this to the top of my “Inspiration” page I keep for myself. This came from Ram’s Wikipedia page.

Good design is innovative
Good design makes a product useful
Good design is aesthetic
Good design helps us to understand a product
Good design is unobtrusive
Good design is honest
Good design is long-lasting
Good design is consequent to the last detail
Good design is concerned with the environment
Good design is as little design as possible
