When I went on to write my next book Working With Emotional Intelligence I wanted to make a business case that the best performers were those people strong in these skills.

We know that there are unaccounted-for Scud and other ballistic missiles in Iraq. And part of the problem is that since 1998 there has been no way to even get minimal information about those programs except through intelligence means.

Ah! yes I know: those who see me rarely trust my word: I must look too intelligent to keep it.

I've done a lot of albums and I kinda know when I'm onto something that was inspirational for me to record and create and this was one of those projects where I really enjoyed making the album.

I'm kind of surprised that so many of those other books were almost exactly like mine. They even follow the form. There were some books that even copied the stamp. It shows so little imagination.

In those days it didn't take much imagination to come up with something that required great lyric development skills. You just thought of an experience that you might have gone through and write it down.

I certainly know there are people in positions of power in the business who lack imagination and perhaps as a result of that think of me as 'David'. But I wouldn't really want to work with those people you know?

We didn't have television until I was about eight years old so it was either the movies or radio. A lot of radio drama. That was our television you know. We had to use our imagination. So it was really those two things and the comics that I immersed myself in as a child.

Now it is quite clear to me that there are no solid spheres in the heavens and those that have been devised by the authors to save the appearances exist only in the imagination.

I think I'm an actor because I have very strong imagination and empathy. I never studied acting but those two qualities are exactly the qualities that make for an activist.
