Any change looks terrible at first.
Any error in any calculation will be in the direction of the most harm.
Any given program will expand to fill all available memory.
Any given program, when running, is obsolete.
Any good strategy will seem ridiculous by the time it is implemented. - Dogbert, in Scott Adams' "Build a Better Life by Stealing Office Supplies: Dogbert's Big Book of Business"
Any horizontal surface is soon piled up.
Any improbable event which would create maximum confusion.
Any issue worth debating is worth avoiding altogether.
Any landing you can walk away from is a good one.
Any line, however short, is still too long.
