Always speak your mind; never say a thing.
Shoot first; ask questions when out of ammunition.
Red sky at night means you're near a sizable city.
Don't count your chickens before they hatch; count your eggs.
Those who fail history might be good at math.
If asked an unanswerable question, give and unquestionable reply.
When in doubt, ask for directions to Rome.
The road less traveled is often a dead end.
A stitch in time saves none.
