Being a disc jockey, whether it be of pop of any variety or classical music, is perhaps one of the most personality-based radio presentation jobs. In this milieu you can become a legend and last a lifetime, as long as you remain versatile and in touch with your audience. Live radio of this kind is a privilege and a joy. Those who do it can often use their fame to access all sorts of other areas of creative work like personal appearances, TV presentation, advertising, after dinner speaking, newspaper columns, training and consultancies. However, it is also one of those areas that is fraught with the worst in-built dangers. The symptoms are an inflated ego, an over-anxious fixation with audience figures, stress and vulnerability to management whims. It’s like most things where the rewards are great, the stakes are high and the drop is swift.
