If, like me, you have many reasons to be less than secure and self-assured, and like me, you are far from stable even on your best days, don't for a moment imagine a psychotherapist will be of more help than a physiotherapist.

I have made so many mistakes, and such really stupid ones, I would start blubbing away if I could remember even half of them. But do not dwell on cock-ups, I say. You don't learn by your mistakes - at least I don't - so best to blunder on making fresh ones.

Few people in contemporary art demonstrate much curiosity. The majority spend their days blathering on, rather than trying to work out why one artist is more interesting than another, or why one picture works and another doesn't.

By and large, talent is in such short supply that mediocrity can be taken for brilliance rather more than genius can go undiscovered.

I don't buy art just to make artists happy any more than I want to make them sad if I sell their work.

Many people cycle or swim to keep trim. But if swimming is so good for the figure, how do you explain whales?
