If you do sign with them, it's very likely you'll have to keep speaking with this person for many years to come. It's important that the two of you get along or it'll just be a burden. The first thing you want to find out is if the company you are joining already has a business plan or some sort of outline for new distributors to follow. If they don't have one, ask your sponsor if they have one. If they don't have one, I would seriously look for a different sponsor or a new company.
Network marketing is all about duplication.
Successful network marketers need to have a system for showing new recruits exactly what they did to become successful. Other training resources you should look for are corporate updates, teleconferences, training videos, and weekly business building articles. Now even if the company and sponsor have these materials you need to do your part by reading, watching, or listening to them. You will NOT get rich quick. Anyone that tells you otherwise is lying.
