It's a genuinely great analogy though, and your particular version is excellent. There's a reason similar sayings have echoed through history.

  "Therefore whosoever heareth these sayings of mine, and doeth them,
  I will liken him unto a wise man, which built his house upon a rock:

  And the rain descended, and the floods came, and the winds blew, 
  and beat upon that house; and it fell not: for it was founded upon a rock.

  And every one that heareth these sayings of mine, and doeth them not, 
  shall be likened unto a foolish man, which built his house upon the sand:

  And the rain descended, and the floods came, and the winds blew, 
  and beat upon that house; and it fell: and great was the fall of it."

  Matthew 7:24-27 KJV
