PCO member Nigel Sutherland says;
I could worry myself about rival cartoonists and agents etc., but that would just lead to unnecessary stress and time wasted. While it’s right to be aware of what’s going on in the “industry” I find it better and more productive to concentrate on what I’m doing and in promoting myself.
