In America we now live more in fear than in hope, and eventually that will lead to ignorance and hatred. We need to have optimism that the world can be a better place, and we can leave a legacy for our children. Being bilingual, travel and studying geography, culture and religions can help.

the people who live in the last places - the people who are most neglected and least valued by the larger world - often represent the best of who we are and the finest standard of what we are meant to become. This is the power that last places hold over me, and why I have found it impossible to resist their pull.

Certainly I am sometimes afraid, but my hope is greater than my fear, and the biggest enemy we all face is ignorance which breeds hatred, whether it be in America, or Afghanistan, or anywhere. We owe it to our children that we may give them all a legacy of peace, but it will take courage and compassion.

I've learned that terror doesn't happen because some group of people somewhere like Pakistan or Afghanistan simply decide to hate us. It happens because children aren't being offered a bright enough future that they have a reason to choose life over death.

I used to climb mountains a lot; I decided to go to Pakistan to climb K2, the world's second-highest mountain. I didn't get quite to the top.

The Koran and Islam is about submission, justice and compassion. All people of the "book" - which means the Torah, Koran and Bible are accorded equal respect under Islam.

The Pathan people of Waziristan are proud people who I greatly admire.
