In an interview, Yvonne Grinam Nicholson, ABC, managing director of RO Communications in Kingston, Jamaica, talked about her career. The historical figure Nicholson most identify with is Mother Teresa. She has this uncontrollable urge to fix and help all and sundry -- sometimes unbidden. Nicholson would explain her profession to a child by telling stories about products, like your toys, your food and other things you love. Knowing her audience is what she had to learn the hard way. She learned this very early in her PR career from sending out more than 100 invitations and setting up an event in another town. If she could choose another profession, Nicholson would be a runway model. For her, the best reward for a job well done is to see a change in people or policies.
