Alisa, the first thing you're going to need to do is learn as much about being a successful agent as possible. Find a mentor, sign up for training classes, learn from your broker, read a lot of articles on the web, etc..
Keep in mind that you're entering real estate at a time that a lot of agents are leaving. It's a tough market and to be successful you're going to have to work that much harder. Also, brush up on your writing skills so that you can communicate effectively on blogs, email campaigns, forums, etc.
Good luck.
