We are so isolated in our own little worlds, in our own little geographies, that it's pretty hard to understand where someone else is coming from. And so I think that we have to really think about what that means as a country and, frankly, whether this segregation that we have is durable over the long run.

As a culture, working-class white Americans like myself had no heroes. We loved the military but had no George S. Patton figure in the modern army. I doubt my neighbours could even name a high-ranking military officer.

We need to think about how we teach working-class children about not just hard skills, like reading and mathematics, but also soft skills, like conflict resolution and financial management.

People in my hometown voted for President Reagan - for many, like my grandpa, he was their first Republican - because he promised that tax cuts would bring higher wages and new jobs. It seemed he was right, so we voted for the next Republican promising tax cuts and job creation, George W. Bush. He wasn't right.

Throughout my life and career, I have continually been impressed with the importance of integrity - whether it was growing up as a Boy Scout, working in one of my first jobs as a university janitor, or being a leader in a Fortune 500 company.

My message to students is that if you want to become an entrepreneur and save the world, definitely don't skip college. But go to a school that you can afford. You'll be freed from the chains of debt and succeed on your own ambition and merit.

I have won things in my career, and people ask why that's not enough. But there can always be more.

One thing I've had to realize in my career is that I can't do it all. Sometimes we put a lot of pressure on ourselves to make sure we're writing the next hit. There are other people out there, and that's what they do every day, and they have strengths that I don't have.
