If it doesn't sell, it isn't creative. - David Ogilvy

The 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.

Suppose you’ve got an acute appendicitis. You’ve got to be operated on tonight. Would you like to have a surgeon who's read some books of anatomy and knows how to do that operation – or would you prefer to have a surgeon who refused to read all books about anatomy and relied on his own instinct? Why should a manufacturer bet his money – perhaps the future of his company – on your instinct?

Encourage innovation. Change is our lifeblood, stagnation our death knell.
