Well, you do have to be at least somewhat outgoing, because you just
gotta strike up conversations out of the blue. You can't really get by with just selling to people you know; as osso pointed out, no one wants a friend bugging them about buying stuff! besides, you'd run out of friends one way or the other
If she isn't at all outgoing, it could be hard for her. It was for me. I
could force myself to approach people about it, and got results when I did, but it was too exhausting for me to keep it up.
But getting started and just seeing if it works for her isn't too expensive. You get the starter kit for $100 plus shipping (and I think tax too). You don't have to order inventory to start with if you don't want to, you can get by with just what's in the starter kit for your first appointments with people. There are also really good deals on samples on ebay -- you're not supposed to buy stuff from there, so she'd have to not tell her recruiter person about it if she did, but it's a much, much cheaper way to get samples, and that's a big help. Way easier to make the stuff look good if you can let people try as much as possible...
