I have learned that nothing is certain except for the need to have strong risk management, a lot of cash, the willingness to invest even when the future is unclear, and great people.

Leadership is an intense journey into yourself. You can use your own style to get anything done. It's about being self-aware. Every morning, I look in the mirror and say, 'I could have done three things better yesterday.'

There is no real magic to being a good leader. But at the end of every week, you have to spend your time around the things that are really important: setting priorities, measuring outcomes, and rewarding them.

I'd be lying if I didn't say there were days when I went back and said, 'I wish I'd done this. I should have done that. I handled this the wrong way.' But it's always in the motivation of getting better. I've never once looked in the mirror and said, 'Oh boy, can't do this one.'

Nelson Mandela was an outstanding leader and a mentor for me. I was in South Africa at the time he was released. I was in South Africa when he was inaugurated as the first president.

Captain America is a matured and a balanced leader. This is something that I am not. So, that made it all the more challenging for me. 'Captain America: Civil War' is bigger, better, and the action is huge. It's a film for kids and adults, and the actual moral of the film is something I loved and believed in. So, I was very happy to voice it.

Conflict, of course, comes about because of the misuse of power and the clash of ideals, not to mention the inflammatory activities of unscrupulous and bigoted leaders. But it also arises, tragically, from an inability to understand and from the powerful emotions which, out of misunderstanding, lead to distrust and fear.

I think we so often equate leadership with being experts - the leader is supposed to come in and fix things. But in this interconnected world we live in now, it's almost impossible for just one person to do that.
