Don't try and remember odds by heart, but rather try and absorb the general implications. Many great players play according to general principles and have no clue of the exact odds.
Like every casino game, don't plan to win every roll of the dice.
Craps superstition - When the dice hit someone's hand, that roll will be a seven. This is why you'll hear so many people shouting: "Watch your hands!" as the shooter starts to roll. Even the casino crew will shout this out and be careful of where they place their hands. Many a craps player has accused the casino of jinxing the roll by letting the dice hit a dealer's hand.
