Excerpt from The Art of Worldly Wisdom by Baltasar Gracián.

cxxx Do and be seen Doing.

Things do not pass for what they are but for what they seem. To be of use and to know how to show yourself of use, is to be twice as useful. What is not seen is as if it was not. Even the Right does not receive proper consideration if it does not seem right. The observant are far fewer in number than those who are deceived by appearances. Deceit rules the roast, and things are judged by their jackets, and many things are other than they seem. A good exterior is the best recommendation of the inner perfection.
