One thing that guides a person in gambling is discipline, the discipline to maintain your gambling account at the minimum balance it started earlier every time that there's an overflow that comes from winning. As you hit a win, you should remove the excess funds into your savings wallet and maintain the initial amount you deposited, then you can continue gambling, the more you win, the more you relocate the funds overflow so you don't loose your profits. As soon as your funds gets exhausted on the casino, its a sign of end of gambling for the day, continue next time. Like that you'll be able to save your profits and loose only that which you deposited initially which is the  amount you could afford to loose. You might even be on very good dividends with the excesses you constantly remove earlier.

Gamble with your head and not the heart, profits should be removed immediately they are present while gambling to prevent HAD I KNOWN.
