To build a strong team, you should first make a plan, for a week and for a month. Try to learn at least one new thing daily, and try to incorporate it in your SFI routine. Advertise daily, using whole lot of media available. Change your ads, blogs and such to find the best combination of words and images. Contact your PSAs and CSAs weekly at least, support them and share your insights and tips. Try to learn from the best.
