I believe that the best strategy in earning quickly with SFI is learning the business itself. What I am trying to say is, even when you have the capital to have Standing Orders that could make you the highest in the Team Leader position but you don't have the knowledge on what is going on with the business, I believe you will not really feel the achievement of being successful with SFI.
It is still best to start from the basic to be successful and learn to grow in time.
