I don't think winners beat the competition because they work harder. And it's not even clear that they win because they have more creativity. The secret, I think, is in understanding what matters.
It's not obvious, and it changes. It changes by culture, by buyer, by product and even by the day of the week. But those that manage to capture the imagination, make sales and grow are doing it by perfecting the things that matter and ignoring the rest.
Both parts are difficult, particularly when you are surrounded by people who insist on fretting about and working on the stuff that makes no difference at all.
