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.

After I graduated from the University of Glasgow, I was a self-employed archaeologist going from dig to dig around Scotland, and it was not well-paid. I was an excavator, not a lecturer as well, so paying rent on a flat was tricky. In the end I decided to retrain as a journalist as I couldn't see a future in it.

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 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 worked on local papers, before taking a job as a webmaster with a very well known telecommunications company in London, as I thought the internet was the future.

I find it so easy to read qualified commentators who are 180 degrees opposed to each other.

People looking at what I do from the outside would think it was a secure world I live in, but it isn't. Just because you had a series last year, doesn't mean you will have one next. But I am quite happy with that.
