Notoriously outspoken, his sentences always punctuated with profanities, General George S. Patton was the epitome of what a leader should be like - or so he thought. Patton believed a leader should look and act tough, so he cultivated his image and his personality to match his philosophy.

It is only from the people I've had the good fortune to meet that I am learning the lessons to guide me. Baz Luhrmann, director of 'Moulin Rouge,' for example, has a childlike curiosity about the world. He doesn't pretend to know all the answers - quite the opposite, in fact. He asks loads of questions of everyone.

Republicans are completely befuddled by Obama's 'star power' and don't seem to have a clear or effective strategy to compete.

I never imagined working with CEOs, congressmen or the military, yet I make regular visits to the Pentagon, stop by the Capitol now and then and sit down with leaders of all kinds of companies.

The most important questions for anybody thinking of running for president are not 'Will you run and can you win?' There is, 'What is your vision for America? And can you lead us there?'

In my experience, it is the leader - the CEO - who plays the crucial role in creating and 'owning' an organization's culture, setting the tone, and executing on that consistently.

My job as a leader is to make sure everybody in the company has great opportunities, and that they feel they're having a meaningful impact and are contributing to the good of society. As a world, we're doing a better job of that. My goal is for Google to lead, not follow that.

One thing that I feel very, very strongly is that we talk about Islamic countries, Islamic people, Islamic leaders, as either moderates or extremists. It's almost like there are only two categories of Muslims. And actually, that doesn't show respect. It shows lack of understanding of the diversity of Muslim thought.
