My gardening apprenticeship was similar to the way a chimney sweep is pushed up a chimney. It was enforced by my parents, non-negotiable - it would be weeding the strawberries, mowing the grass.

Having a Mary Poppins-themed birthday party when I was 5 - all my friends went in dresses, and I went as a chimney sweep. I was a real tomboy.

We all ought to understand we're on our own. Believing in Santa Claus doesn't do kids any harm for a few years but it isn't smart for them to continue waiting all their lives for him to come down the chimney with something wonderful. Santa Claus and God are cousins.

I have discovered the secret of happiness - it is work either with the hands or the head. The moment I have something to do the draughts are open and my chimney draws and I am happy.
