I know Donald Trump quite well. We've never shared values, he and I. But I respected his ability to turn it around. So I respect somebody who can turn things around and be successful. I think the president's communication style is the most difficult thing because he actually does care, people who know him know he cares. But his style of communication, his combative approach, the elements of ego that are obviously there in all of us but seem to be more easy to see in the president sometimes than other people, get in the way of his capacity to lead, unfortunately.

The secret to successful hiring is this: look for the people who want to change the world.

Presentation skills are key. People who work for you represent your brand. You want them to present themselves - and represent you - in a certain way.

One person at a time, one company at a time.

I just cannot understand why we can't have better schools. That private schools are the only option for the kind of high-net-worth crowd, I think, is ridiculous. It should be a major initiative. It should be something we're all working on. We have to get our head out of the clouds.

You have chosen the wrong path if it's not fun. And you are probably not taking enough risk if it's not hard and rocky sometimes.

You must always be able to predict what's next and then have the flexibility to evolve.
