How to get into the Motocross world?

Sorry guys it has been a long time since I have been on just trying to figure out what I want to do most in motocross. I know that there are a lot of things about motocross that we love, but finding that one thing that makes you be round out at all times is what I search for. I have been a business owner for over 20 years and have loved motocross my hole life. I have been to tracks all over the United States and have always had the passion to work in the motocross industry. I have finally decided to try to find what I have been desiring for so long. I do not care what I have to do to start my new adventure because I know once I am in I will move up the ladder. I know you have to start somewhere and I am prepared to do so. If there are any suggestions in how to make this happen they are all welcome. So hope to hear from all of you motocross fans.
