4 Timeless Arthur C. Nielsen's Marketing Guidelines.
Nielsen's Personality is reflected in the guidelines he set for his firm in 1931, some of which were, in part; 1. Be influenced by nothing but your client's interests. Tell them the truth. 2. Charge enough to do a thorough job. Then do a thorough job regardless of the cost. 3. Watch every detail that affects the accuracy of your work. 4. Leave no stone unturned to help your client.
