The informant heard this proverb from an older man one day at work.  The man told him, with a smile, “Don’t do anything you wouldn’t do twice.  Don’t do anything you wouldn’t do twice.”  The informant laughed upon hearing this, but still remembers this proverb years later.  The informant thinks there is wisdom in this proverb, but doesn’t agree with it entirely–and he thinks it is most true when the “anything” involves a huge risk.

One immediate rebuttal of this proverb that popped to mind is–try everything once.  But there’s certainly things that should never be tried, and plenty of things that should be done twice.
