First, “Nothing is impossible” is patently false. Is it impossible for anything to be impossible?
Of course, in conventional usage, the statement is hyperbole for something like “Many things that seem impossible are not”, meant as encouragement; stronger than “Never give up” or “Try harder.” The skeptics among us aren’t buying it.
Of interest here is the sense in which it is apparently a corollary of “Nothing is perfect.”
