This is the way, I feel. But sticking to it is difficult.
My best friend Chuck would follow any fad or trend, and he got into amway. He wanted everyone to be in the same club he was getting such validation in. He proselytized like mad. We told him no.
He kept asking and offering and trying to show the pitch videos. We told him no; and that the third time he tried this it'd be the last we saw of him.
I hope he's doing well and broke free of those guys. It's been 28 years, I'm sure. But we haven't spoken to him since a few days after the ultimatum.
