Famous quotes containing the words general and/or clients:
“Hence that general is skilful in attack whose opponent does not know what to defend; and he is skilful in defense whose opponent does not know what to attack.”
—Sun Tzu (6th–5th century B.C.)
“...a lot of my people are models. I like that for them. I admire models, so I think that’s right for my people. ...I love it when I have an important [client]. And the pictures and awards. One of my clients has these television awards—a beautiful statue of a woman. I think it’s an Emmy. People would be lucky to get one. She has two. I think that’s great.”
—Elaine Strong (b. 1934)
