The most important thing you should have in gambling game is controlling yourself. Nothing else. By controlling yourself, you will be able to know when it's time to quit, how much money you can use in the bets and else. Controlling yourself will not easy to do because you need to have a strong mind to be able to stop in anytime.
It is greediness that makes many gamblers to actually lose money. There is always a time to quit and most times that is when the sweetness of making money do push many of us to start over gamble for profits. Whenever you are over gambling you should be rest assured that you are already on the part of losing heavily.
Not for me now, personally my experience help me a lot not to loss more money, I loss but a small amount of money and I can easily forget it.
What experience told us for most gamblers, is that we learn the ability to minimize our loses, and that's better than expecting to win when we don't have the capacity.
Experience is truly a great teacher. Its unfortunate that many would never learn. I didnt even need experience to understand that in gambling, it is good to play with what can easily be forgotten or any amount that I can easily afford to loose.
It was so easy for me to always gamble what I can easily afford to loose because I saw gambling as a game of entertainment. I knew I didnt have to commit an amount that was too much for me just because I needed fun, and I quit the game as soon as I exceed my limit even though I do not make any profit, I will just be glad I had fun and that is all that matters more to me.
