Focus becomes a design I think there is an important law of design, that is comfort is appropriate enough, stop where it should stop. Some designs, after bedecked and revised, it was not satisfying, revised and revised, and again, it wasted a lot of time and energy. But when you stop revising, then use it, focus on this opus, it becomes a whole opus, if use it for a longer time, this feeling is more obvious. Design is to found the basic platform, this platform is simpler and easier to use, that is better, because it's easier to be focused on. The simpler platform, the expansibility is better. The design which can be used again and again, and can be focused on, that is a living design.
