Good or bad, most advice gets repeated by people with only half a clue as if it’s the undeniable truth. Causing hundreds of people to believe one and all things, which sooner rather than later leads to confusion in the masses.
My rules are:
Do not repeat anything you’re not fully certain about.
Do not repeat anything you know to be a lie.
Do not repeat anything you will not sign your name to.
And do not expect to not be hypocritical in your words from time to time.
