The world has fundamentally changed. It fundamentally changed when the Berlin Wall came down and the 'evil empire' ceased to exist. We are engaged around the world whether we like it or not.

There is no question that al-Qaida operatives are currently active in Iraq. A premature exit before the threat they represent has been dealt with would endanger America and the prospects of eventual peace in the Middle East.

To me, living in the present means being aware of your conscious choice to focus on the past, present or future - it is not necessarily having to focus on the present.

Your life is the sum result of all the choices you make, both consciously and unconsciously. If you can control the process of choosing, you can take control of all aspects of your life. You can find the freedom that comes from being in charge of yourself.

True popularity comes from acts of kindness rather than acts of stupidity.

Success is not in what you have, but who you are.
