In business, the idea of measuring what you are doing, picking the measurements that count like customer satisfaction and performance... you thrive on that.

Marketing is about values. It's a complicated and noisy world, and we're not going to get a chance to get people to remember much about us. No company is. So we have to be really clear about what we want them to know about us.

My model for business is The Beatles: They were four guys that kept each others' negative tendencies in check; they balanced each other. And the total was greater than the sum of the parts.Great things in business are not done by one person, they are done by a team of people.
