The question is not whether you’ll be able to hang on as much as whether you’ll want to. This is a young person’s job. It’s something to do for a few years while making contacts and learning the industry from the inside out. Once you’ve had your fill of the abuse, the long hours, the lack of freedom and the strain on your personal relationships, you’ll be out of there. If you come across any 60-year-old Celebrity PAs, pass along our condolences.
