When I first started working on 'Secret Diary,' I definitely felt like I needed to shape up. The idea of being in my knickers on TV was a great incentive! Now I try to eat right, and I go to Bikram yoga three or four times a week. I have my 'naughty' days, and I indulge in pizza and cake, but so what!

After decades spent in rewrite rooms surrounded by other shouting writers, I discovered that I work best alone. I like being in charge of my time, working out the problems according to my own rhythms and being able to nap. That's a big one, the napping on demand!
