In my own opinion the best way to build a TEAM is to first understand what SFI stands for and the benefit you can derive from it. Then start to teach others want you know and how you have been succeeding with SFI through this medium your team members will build confidence in you and start to share their mind with you.
In addition, you can splash your team members with gifts such as Tcredit etc. and finally be ready to answer their questions anytime with prompt reply.
