A brand is a personality and personalities like people don’t really change so neither should your brand.

“Every advertisement should be thought of as a contribution to the complex symbol which is the brand image.
– David Ogilvy, regarded as the Father of Modern Advertising

“It took millions of years for man’s instinct’s to develop. It will take millions more for them to even vary. It is fashionable to talk about the changing man. A communicator must be concerned with unchanging man, with his obsessive drive to survive, to be admired, to succeed, to love and to take care of his own”
– Advertising great, Bill
