My responsibility, our responsibility as lucky Americans, is to try to give back to this country as much as it has given us, as we continue our American journey together.

Don't be afraid to challenge the pros, even in their own backyard. Learn from the pros, observe them, seek them out as mentors and partners. But remember that even the pros may have leveled out in terms of their learning and skills. Sometimes even the pros can become complacent and lazy.

In the military we are always looking for ways to leverage up our forces. Having greater communications and command and control over your forces than your enemy has over his is a force multiplier. Having greater logistics capability than the enemy is a force multiplier. Having better-trained commanders is a force multiplier. Perpetual optimism, believing in yourself, believing in your purpose, believing you will prevail, and demonstrating passion and confidence is a force multiplier. If you believe and have prepared your followers, the followers will believe.

There's no doubt in my mind, though, that the Iraqi people would be better off with a different leader who did not waste their oil on weapons, as opposed to education, as opposed to healthcare, as opposed to food, as opposed to roads, as opposed to clean water.
