The one thing I can say is to do some in depth research as to exactly what CRM is and get in touch with some persons that are already in the field. If one is close to you then possibly see if you can shadow them during a day in their work or interview them as to what they like/dislike in the job. Make sure that it is something that you would love doing. Please don’t follow the days of the dot com bubble and get into a field just because of the pay. You should love the job first, the money second.
