Throughout my career, I have lived by the principles of personal honor and professional integrity.

What I'm trying to do is teach people how to actually get individuals in organizations to do the kinds of things to make a difference. It starts with not just studying the mechanics but really understanding how people operate.

Our bureaucracy had excelled at compartmentalizing intelligence - we had a 'need to know' system - but by 2004, it was impossible to foresee what elements of our organization would and would not need to know a given piece of information.

In our society, I see public media as a lever. It pushes people by elevating them and their sights. It brings them into more thinking and understanding, and it brings us together.

Our health-care morass is like the problems of global warming and the national debt - the kind of vast policy failure that is far easier to get into than to get out of. Americans say that they want leaders who will take on these problems.

Government leaders should get up to speed on the blockchain by understanding it first and committing to exploring its potential.

Like Siemens, the UAE is big on innovation. It has become famous as a think tank for thought leadership in areas of interest to the world - and to Siemens.

I don't know what leadership is. You can't touch it. You can't feel it. It's not tangible. But I do know this: you recognize it when you see it.
