Health innovation, enabled by digital technologies to build big consumer service brands, is an incredibly interesting, complex problem to work on.

The healthcare industry has never had a priority on user experience because there has been little competition. Prices have never been transparent.

One thing about Apple is they have these fanboys - as I always say, 'Sell to the people who love us.' For example when they came up with iPad mini, everyone who had an iPad went out and bought a mini as well.

Stay the course and keep building an integrated Apple ecosystem of iPhone + iPod + iMac + iTunes + App Store + Apple TV. No one has yet demonstrated they understand how to create an 'experience-based ecosystem' as well as Apple.

I've spent my whole literary career blurring boundaries between genres and categories.

I don't think I ever saw acting as an actual career until late.

I've been here 21 years, and I literally did walk up and down Music Row trying to break into the business. I felt very free to go into any publishing company.
