Good design is simple
Beauty should depend on a few carefully chosen structural elements rather than a profusion of superficial ornament.
Good design is timeless
If you want to make something that will appeal to future generations, one way to do it is to try to appeal to past generations.
Good design solves the right problem
Good design is suggestive
In architecture and design, this principle means that a building or object should let you use it how you want.
You should give users a few basic elements that they can combine as they wish.
Good design is hard
You want the kind of pain you get from going running, not the kind you get from stepping on a nail.
Good design looks easy
You have to get them in exactly the right place. The slightest error will make the whole thing collapse.
Good design uses symmetry
There are two kinds of symmetry, repetition and recursion.
The danger of symmetry, and repetition especially, is that it can be used as a substitute for thought.
Good design is redesign
They (experts) play for plans to change.
Mistakes are natural. Instead of treating them as disasters, make them easy to acknowledge and easy to fix.
Good design can copy
Unknowing imitation is almost a recipe for bad design.
The greatest masters go on to achieve a kind of selflessness. They just want to get the right answer.
Good design happens in chunks
Nothing is more powerful than a community of talented people working on related problems.
