"We were talking about MLM ‘grinders.’

These are the ‘loyal soldiers’ who soldier on year after year,
but never really breakthrough to achieve the big bonus checks,
recognition, and lifestyle the industry promises. They work
hard, do all the stuff their sponsor or company tells them to,
but they never really get the payoff.

This is a tragedy. And unfortunately it happens all the time.

The reasons are numerous. But mostly they can be traced to one
deciding factor. They have a sponsorship line who has never
really breathed the thin air at the top, so they don’t know how
to coach and guide their people there. They keep handing out
the same marketing materials, making the same presentation, and
spouting the same clichés.
