The world is more peaceful and more free under my leadership.

Fool me once, shame on - shame on you. Fool me - you can't get fooled again.

Leadership to me means duty, honor, country. It means character, and it means listening from time to time.

Terrorist attacks can shake the foundations of our biggest buildings, but they cannot touch the foundation of America. These acts shatter steel, but they cannot dent the steel of American resolve.

Freedom itself was attacked this morning by a faceless coward, and freedom will be defended.

Our enemies are innovative and resourceful, and so are we. They never stop thinking about new ways to harm our country and our people, and neither do we.

Freedom is not our gift to the world it is God's gift to humanity.

To those of you who received honours, awards and distinctions, I say, well done. And to the C students, I say, you too can be president of the United States.

I like to think that life lessons are learned and re-learned every day and take on importance at different times in life.

I also surround myself with good people who keep me and bring the best out of me. I don't generally hang out with crazy people.

The lazy manage to keep up with the earth's rotation just as well as the industrious.

I'm a nine-year old kid inside and my passion has been all my life to want to travel into space.

The world of tomorrow belongs to the person who has the vision for today.
