Cameron Diaz has ADD, or attention deficit disorder, which can make many sufferers unable to focus on one task for a prolonged amount of time.
She told OnTheRedCarpet.com in January 2011: 'I have no interest in directing movies or producing movies. I like my role in making films. It's the perfect amount of involvement for me. I have ADD. I would never be able to spend two years making a movie or even one year. I would just, I'd be someplace else within a few short moments.'
