Common sense, will power & discipline are three traits you need to exhibit while playing in the casino. What does this mean? You can’t play with money that you cannot afford to lose. Leave your ATM card and check book at home. If you're behind, don't get upset or try and play longer to get even. The main reason most players lose is because they don't quit when they are ahead. Therefore, if Lady Luck smiles on you and you end up with more chips than you started with, scoop up those winnings and walk away a winner!
