"Every day the market you work in—regardless of the industry—asks 'Are you invaluable?' Did you answer the question satisfactorily today? Well done. Get ready to answer it again tomorrow. As the speed of innovation and information ever quickens, so does the need for you to have clear answers for this 'invaluable question.' It is no longer enough to simply have a job. It is no longer enough to simply advertise and attract customers to work with you. Loyalty to employees, to brands, to personalities and to media disappears the instant one's attention is switched to new, shinier options."
