What I've realized over time, is don't try to "sell" a concept, rather try to "hook" others to it. If you are trying to "sell it", others are like "ah, ok, so why is he trying to get me in?"... something like that... instead, if you just mention that you posted something and that post earned you X, it might make people ask questions and then lead to a process of "onboarding". But it has to be on some irrelevant conversation or something...
