Many years ago we lived in Milton Keynes, where Amway had it's main distribution centre, a mate at work invited me and Mrsjova to a 'life-changing' event. Being newly married with a mortgage, young baby and just out of the Army we were up for anything that promised extra money for little effort.
It was an Amway presentation and we lasted about an hour, mainly out of loyalty to a mate, but it had taken about 10 minutes to realise you were working for other people's benefit without any guarantee of payback.
He was so convinced that he was going to make a fortune from it that he quit his well paid job and decided to live off the Amway income.
Next thing I heard, about 18 months later, was a copy of his CV landed on my desk when we were recruiting engineers. The intervening period was shown as 'Travelling the world'. I invited him for interview as he had skills we could use but I never heard back from him.
