I used to be a demonstrator and to be honest, we only used to say that to people who we honestly believed had the 'talent' KWIM?
I did enjoy being a demonstrator, the only bad thing is i was expected to travel 2 hours every week for meetings - which just wasnt suitable for me having a young baby.
You meet lots of new people which is great!! I still have people stop me on the street who remember me from doing their parties.
You have nothing to lose if you give it a go!!!! i say go for it!!!!
