I don't look at what people do with their homes in terms of money, but the social and personal value of what they're trying to do and achieve.

I spend a frightening amount of money on books.

Generally speaking, I think that if you do anything with commitment and passion, it will come good.

The thing that I champion is sustainability. My terror is that suddenly we see it as a luxury, not an essential. That's a danger.

Sustainability is now a big baggy sack in which people throw all kinds of old ideas, hot air and dodgy activities in order to be able to greenwash their products and feel good.

A great deal of energy is wasted in hating people, and I can honestly say I've no wish to expend such a precious resource on being outraged about anyone.

I've forgiven all my enemies - even those who have stolen money from me.
