The best way to measure your success in SFI is watching your business grow.
If you have more CSA's and PSA's in your genealogy than the previous month, if you are able to encourage them and motivate them to make their own business grow and so make your business grow, if you connect every day and check your to-do list and earn your daily VP, if you participate in each and every game daily...this is the way to measure your success (not only taking into account your gainings and commisions)
