At various times there have been high profile people who say that they are determined not to be swallowed up by their celebrity/talent. Think Kate Winslet, or even the Duchess of Cambridge, gradually the need for domestic support, whether Granny as Nanny (D of C, Cherie Blair) or/and personal assistant (both), creeps on them, bit by bit their career takes over their lives.
For some the machine takes over the individual. It has come out in court what a difficult person, to put it mildly, Charles Saatchi would be to live with, even if the marriage was happy. I think all of us know what it is like when a relationship is fractured, how all encompassing it becomes, like a set of blinkers, while you struggle on trying to keep all the plates in the air. I can see in the circumstances how the principal becomes the client of the support system.
