Catherine Zeta-Jones

I allow myself to not feel the need to be some sort of wonder woman. You can't do everything at once and tear your hair out when you miss your baby using a potty for the first time, although my son was obviously very sad that his mum was not there on his big day.

The thing about dancing - what it taught me all those years - is it gives you an amazing sense of discipline in forcing yourself to do things that you know are good for you but you don't really want to do.
