Brave people don't live forever, but cautious people don't live at all.

The best advice I could give anyone is to spend your time working on whatever you are passionate about in life.

There is no planet B. We have to take care of the one we have

I don't live my life thinking about "if only." I just try to think positively about the future. We'll never know for certain what would have happened if we'd gone to Iraq. The important thing is that we've got to do everything we can to prevent other wars.

You never know with these things when you're trying something new what can happen. This is all experimental.

Just start. You will learn so many lessons just by doing.

Whatever business you are in, every company can shoot for the start in their own way.
