Building a team is soooooooooo very important to achieving success in SFI.  

Here's why:
It doesn’t matter how intelligent, rich, energetic, or dynamic you are—we are all limited to the same 24 hours a day. By sponsoring other affiliates, however, you can overcome this limitation. By sponsoring, you can essentially clone yourself and have dozens, hundreds, even thousands of people all working indirectly on your behalf on their time—and receive a percentage of everything they earn!
Sponsoring affiliates also builds security for your business. Why? In most traditional businesses, what happens if you become ill or disabled and are unable to service your customers? Or perhaps you just want to take a vacation. Whatever the case, you could lose most, if not all, of your income overnight because it relies on your being there. That’s not owning your own life, and that’s certainly not financial freedom!

Through the process of sponsoring affiliates, however, you can create total financial freedom for yourself. When you've sponsored your own team of independent business people, you no longer have all your eggs in one basket. On the contrary, because each person on your team has a vested interest in continuing and building his or her own businesses, you create an income that is not dependent upon you—an income that can continue, even grow, indefinitely, with or WITHOUT you!
Now read the above three paragraphs again, and make sure it sinks in, because it is one of THE most important things you'll ever learn at SFI.  Build a team, and you'll build success.  Don't ever forget this.  And always keep team building amongst your highest priorities!
