We live in a world where there are a hell of a lot of new inputs that need to be factored in to your business. It used to be just about your employees and your customers. Now there are all the issues about global warming, about sustainability, about ethics and now about gender and the distribution of wealth.

I think that business leaders today have to be more rounded than they used to be, they have to be completely multi-functional and fast-moving.

When I got married in my twenties, I had a happy marriage and happy kids but at some point in time I let it go off the rails I let it go off the rails.

Was I the best husband? No. And I regret it.

I don't believe in retirement.

When my mother died, my father was in a crisis, my sister was in a crisis, everyone was in a crisis. I went round the night my mother was lying in the kitchen, and I organised everything, from the undertaker to the funeral... I looked after everybody, I sorted it all out and Ive done so ever since.

I actually think the whole concept of retirement is a bit stupid, so yes, I do want to do something else. There is this strange thing that just because chronologically on a Friday night you have reached a certain age... with all that experience, how can it be that on a Monday morning, you are useless?
