Going into the year, our No. 1 challenge was to improve sales trends at Taco Bell and KFC, and I am encouraged by progress at both brands,

Their immediate challenge, ... is to give us a fresh creative approach to help improve sales.

The idea is not to increase intensity, but to challenge your body by forcing it to recover more quickly.

Digital sales aren't growing fast enough to replace the losses in our traditional business. The challenge for the industry is to find some balance between singles sales and album sales. We want to create an artist experience, not a singles experience.

It is crucial that we time our new products ahead of major events. My biggest challenge is whether our sales strategy will be strong enough to compete with bigger rivals on a global scale.

The accelerated sales pace of recent years has all but ended, and we're returning to a more normal market.
