I don't know anyone who is more admired and respected in the international community than President Karzai, for his strength, for his wisdom and for his courage to lead this country first in the defeat of the Taliban and now in rebuilding a democratic and unified Afghanistan. And I can tell you I am with foreign ministers and with heads of state all over the world. I sit in the councils of NATO. I sit with the EU. I sit with people all over the world and there is great admiration for your president and also for what the Afghan people are doing here.

Everybody in the world is capable of democratic development. Some people in the world are unlucky enough to get stuck with really bad political leadership and with really bad political institutions.

We can't live true to our set of values unless American educational system is strong. I really believe that if we don't get that right we will not compete because we won't believe that our people can compete, and we'll turn inward. We won't lead. That will be bad for the world.

Life is full of surprises and and serendipity. Being open to unexpected turns in the road is an important part of success. If you try to plan every step, you may miss those wonderful twists and turns. Just find your next adventure-do it well, enjoy it-and then, not now, think about what comes next.

It's bad policy to speculate on what you'll do if a plan fails when you're trying to make a plan work.

Self esteem comes from achievements. Not from lax standards and false praise.

You know, life is not one in which you just get to choose the things every day that come easily to you. And it's also true - and this is the self-esteem problem - you learn that there are people who are better at things than you are.
