I met my grandfather just before he died and it was the first time that I had seen Dad with a relative of his. It was interesting to see my own father as a son and the body language and alteration in attitude that comes with that and it sort of changed our relationship for the better.

I've reached a point in my life where it's the little things that matter... I was always a rebel and probably could have got much farther had I changed my attitude. But when you think about it I got pretty far without changing attitudes. I'm happier with that.

I was very much into buying contemporary art but I've just decided I want to get rid of it all. Not that it's not great art but all of a sudden my mood has changed and I want to go back to seventeenth- and eighteenth-century masters.

Early-twentieth-century abstraction is art's version of Einstein's Theory of Relativity. It's the idea that changed everything everywhere: quickly decisively for good.

Until the Eighties Oslo was a rather boring town but it's changed a lot and is now much more cosmopolitan. If I go downtown I visit the harbour to see the tall ships and the ferries and to admire the modern architecture such as the Opera House or the new Astrup Fearnley Museum on the water's edge.

We are not the same persons this year as last nor are those we love. It is a happy chance if we changing continue to love a changed person.

Winning 'The Apprentice' changed my life in ways I could never have imagined. It has been an amazing experience working for Donald Trump and I am very grateful for the whole opportunity.

We're all doing different things and some of the girls are mums so priorities have changed. But I would love to do something with the Spice Girls again. I know we would have an amazing time.

I always say I'm certain I changed 'Watchmen' less than the Coen brothers changed 'No Country for Old Men.' I'm certain of it. But you don't hear the Cormac McCarthy fans like up in arms about it. They should be. It's like an amazing Pulitzer Prize-winning book.

What I'm trying to do is get this message out about self-empowerment entrepreneurial spirit and true Americanism - the way we were when we changed the world when Edison was alone failing his 2 000th time on the lightbulb.

You could say in a vulgar Freudian way that I am the unhappy child who escapes into books. Even as a child I was most happy being alone. This has not changed.

We are the children of a technological age. We have found streamlined ways of doing much of our routine work. Printing is no longer the only way of reproducing books. Reading them however has not changed.

One of my grandfathers actually having gone out there as a minister decided he would better serve the people as a doctor. So at a very late age - at the age of 38 in fact - he changed course and decided to become a doctor.

My dad encouraged us to fail. Growing up he would ask us what we failed at that week. If we didn't have something he would be disappointed. It changed my mindset at an early age that failure is not the outcome failure is not trying. Don't be afraid to fail.

The great secret that all old people share is that you really haven't changed in seventy or eighty years. Your body changes but you don't change at all. And that of course causes great confusion.
