You may have only been a model for a couple of years, however, the network that you have built in that time can really help you build a career in acting as well. Especially since you have already built relationships with many agents, casting directors and other peers during that time. The connections you have now can help you forge more connections as you become an actor. You may find that the agency you are already working for works with actors as well or your agent may even have someone in mind to refer you to when you change your career path. That person they refer you to will already have a good reputation and will be able to help you as you continue down your path and help expand your network even further. It does pay to know someone who knows someone else and so on and so on.
