David Ogilvy once said I have a theory that the best ads come from personal experience. Some of the good ones I have done have really come out of the real experience of my life, and somehow this has come over as true and valid and persuasive.
In 2017, Jeff Bezos wrote to Amazon shareholders- "A customer-obsessed culture best creates the conditions where all of that can happen."
They are both referring to the intuition and insight on the customer. In my belief, working in marketing strategy is similar to trying to solve similar problems with via different formulas. Except that there's no formula to evaluate human psychology and our reactions, response, decisions to the world around us....
