You have to define what success is to yourself first.
To some working 80 hours a week is success. To other making as much money as possible is success and to others have the most agents and biggest brokerages is success.
The one I used to be a part of is
www.solidsource.comThey are one of the most successful 100 percent companies I have ever seen.They grew from 80 agent when I joined to over 2,000 plus now.
Now that I have my own company success to me is to work no more than 40 hrs a week and do real estate deasl along with my investing.Take time off to travel and spend with the family each year and be fullfilled not just monetarily but spiritually,emotionally,and physicially for COMPLETE success.
My advice is decide how you imagine your brokerage to be an create action and business plan around it with specific goals and steps.
