I wasn't the kind of kid who would get A's without even trying. I had to work to get good grades, but I was very organised about it because I always wanted to do well at everything I did. I'm very competitive.
I was an excellent student before I left school. But I graduated early so that I could work longer hours on '90210.'
If you had a national grid with one operator, you had twenty or even a hundred operators, if you don't have the ability to compel people to observe high standards of conduct, then you run a greater risk.
