I never tell one client that I cannot attend his sales convention because I have a previous engagement with another client; successful polygamy depends upon pretending to each spouse that she is the only pebble on your beach.

The worst fault a salesman can commit is to be a bore...... Pretend to be vastly interested in any subject the prospects shows an interest in.

I avoid clients for whom advertising is only a marginal factor in their marketing mix. They have an awkward tendency to raid their advertising appropriations whenever they need cash for other purposes.

Repeat your winners. If you are lucky enough to write a good advertisement, repeat it until it stops selling. Scores of good advertisements have been discarded before they lost their potency.

Much of the messy advertising you see on television today is the product of committees. Committees can criticize advertisements, but they should never be allowed to create them.

I can't stand callow amateurs who aren't sufficiently interested in the craft of advertising to assume the posture of students.

If you have all the research, all the ground rules, all the directives, all the data - it doesn't mean the ad is written. Then you've got to close the door and write something - that is the moment of truth which we all try to postpone as long as possible.
