What I learned most was how to tell a story in 15 seconds or 30 seconds or 60 seconds - to have some kind of goal of what to try to do and make it happen in that time.
I try to work out with my personal trainer for an hour, four times a week - we mainly concentrate on weights and running. If I'm on the road I sometimes do DVD work-outs in my hotel room - P90X and Insanity are a couple of my favourites.
