Most people in NLP choose either business or personal growth and development. Since you have a solid background in business you should stick to the path the horse or riding for at least the beginning of your career. As time goes on, even if you start working in business, people will come to you and ask for help in problems with their kids, health and fitness, relationships, etc. But for now, go in the area of your expertise, and find a path that you can excel in. More about the niche and HOW specifically to do this will be in the next projects.
