When I can look life in the eyes grown calm and very coldly wise life will have given me the truth and taken in exchange - my youth.

In fact men will fight for a superstition quite as quickly as for a living truth - often more so since a superstition is so intangible you cannot get at it to refute it but truth is a point of view and so is changeable.

Let's say a Soviet exchange student back in the '70s would go back and tell the KGB about people and places and things that he'd seen and done and been involved with. This is not really espionage there's no betrayal of trust.

Citizens the priority now is to recover trust between the Egyptian - amongst the Egyptians and to have trust and confidence in our economy and international reputation and the fact that the change that we have embarked on will carry on and there's no going back to the old days.

But that citizen's perception was also at one with the truth in recognizing that the very brutality of the means by which the IRA were pursuing change was destructive of the trust upon which new possibilities would have to be based.

Some of their best songs don't have bridges and choruses. So that made me think I should trust my instincts. My songs were okay I figured. I didn't need to change anything.

People make suggestions on what to say all the time. I'll give you an example I don't read what's handed to me. People say 'Here here's your speech or here's an idea for a speech.' They're changed. Trust me.

Time travel may be achieved one day or it may not. But if it is it should not require any fundamental change in world-view at least for those who broadly share the world view I am presenting in this book.

I'm a big fan of doing 'Triple D.' But I don't want to do it forever don't get me wrong! Travel away from my family are you crazy? But do you know what it does for these mom-and-pop restaurant joints? It changes their lives forever. I mean their businesses will never be the same.

When you're an artist there's always a moment in your life when you think you're not inspired and instead of doing things and instead of travel and instead of falling in love you're just depressed so you don't move so you don't change. So you're not inspired.

The idea is to have global standards. There is so much travel that if you just had a regional standard it would probably ultimately have to be changed.

For many years it seemed as if nothing changed in Norway. You could leave the country for three months travel the world through coups d'etat assassinations famines massacres and tsunamis and come home to find that the only new thing in the newspapers was the crossword puzzle.

Each day as I travel through downtown Tucson I am amazed at how quickly the most ancient of human behaviors have changed. For as long as there have been Homo sapiens - roughly 200 000 years - people have filled their lives principally with two activities: talking directly with other people and doing physical things.

To get away from one's working environment is in a sense to get away from one's self and this is often the chief advantage of travel and change.
