I have always considered that the true test of a machine is its practical utility in the hands of the common laborer.

The more uncertain and insecure I feel, the more I cling to the idea of painting.

The world is full of stories, but the stories are all one.

The question isn't who is going to let me; it's who is going to stop me.

真理还在穿鞋的时候，谎言就走遍了半个世界。

没有听到不如亲耳听到，亲耳听到不如亲眼见到，亲眼见到不如清楚知道，清楚知道不如亲自实践。
