My father was a self-employed, commission-only salesman. He sold double-glazing and fitted kitchens, amongst other things. As he never declared himself unemployed, there was never recourse to benefits, so if money was tight, money was tight. It taught me that we were a closed unit, and that we had to be resourceful.

My wife has always supported me in my career, even when there were times when it was more sensible to get a job. It has been her confidence in me that has helped enormously.

It is security that I crave and money provides security. What is that old line about money? "Some is good, more is better and too much is just right."

I trust to luck. I am planning to be a millionaire before I die but I don't have a plan as to how that will happen.

My father's example taught me self-reliance, to make my own luck, and to work to make things happen.

I have always been quite careful when I have been approached to do a television project to have the option of writing the accompanying book.

It took me a while to get established - success didn't happen overnight.
