Its the same as any place that you would sell real estate, takes time, dedication, never give up, keep going, marketing yourself along with properties, and getting the leads. I think its also very important what office and Broker you pick to work with as they are your support team and the ones that help get you where you want to be selling in your market areas.
I lived in the OC for 23 years and used a lot of agents that had no skill set, and others had a great deal of skills and knew what they were doing in a short time of selling.
I have found selling real estate in a short time in Connecticut that a great broker is worth their weight in gold when they support your career and help you as much as they can as long as you are willing to go the extra miles and do the work. Its all up to you at the end of the day, what you put into it is what you get out of it = )
