我这一代人最伟大的发现是，一个人可以通过改变态度来改变他的生活。

Be yourself; everyone else is already taken.

Color is my day-long obsession, joy and torment.

Representation of the world, like the world itself, is the work of men; they describe it from their own point of view, which they confuse with the absolute truth.

过去是人第一，未来必须是系统第一。
