I think that the best way to convince someone to try SFI is based on the experiences you've had yourself with SFI.
Personally, I convince others by saying that in SFI, you get to LEARN a lot and at the same time you get to EARN as well as you LEARN...
SFI is absolutely FREE....
SFI business depends on the affiliate on how you would like it to grow...
It is global and you get the opportunity to be friends from anywhere in the world as you develop your own business together with the SFI family...
There are so many ways to convince other to try SFI....But what made you try SFI is the best way to convince them for you own the experience yourself...
