Selling Organic food and stuff. Look at your market before
enaging into any venture. MLM is a form of business venture, though
I may get flamed by those anti-MLMers. 
U invested in the company for the
product, the business model and the market potential. Because of
the nature of MLM business, your initial contacts are on top
priority are people that u know, like your friends and relatives.
Try asking this question to yourself, "do they need this product?"
Though some people tink everyone is a prospect, but not so.
Otherwise, your presence is not necessary. Try talking to the
senior leaders in the company about how they succeed, if they are
good enough, they will most likely be full-timing this "career",
otherwise think again about joining that particular company.
Please do more research on the company profile, how long it is
here. The kinda age group that is in the company cos from my
knowledge WBG consists of mainly young people. A good MLM company
has a good "marketing" mix of matured and young people, around
5~10% fulltimers is considered a healthy one.
Look around at other companies, not juz this, there are also other
opportunities around. Make a bench mark, like how much time you can
commit with comparision with the quota some have, whether it is
realistic for you, what is the maximum payout they can give,
whether there is demotion if u r not active for some time (due to
problems, high key 3 weeks reservist).
Juz some pointers.
