David OgilvyThe 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.
David OgilvyThe creative process requires more than reason. Most original thinking isn't even verbal. It requires 'a groping experimentation with ideas, governed by intuitive hunches and inspired by the unconscious.' The majority of business men are incapable of original thinking because they are unable to escape from the tyranny of reason. Their imaginations are blocked.
