Beginners are the ones that have such optimism but it slowly fades away when they realize that their dreams cannot really be achieved with gambling. As a novice you'd be quick to believe in certain strategies you see online or the ones you come up with by yourself. The more mature you become you'll realize that nothing about gambling is sure, it's just a game of luck, those that don't realize this on time end up losing more
And instead of them to learn to play by they always feel like they know enough already and it is usually not so and this are why when things don't go the way they want they start looking for who to blame exactly and they like blaming the casino wereby they are the cause of the problem. And most of the problem they have is greed they find it very difficult to control but the only way you can free your self is to control your emotions so that you don't be like people that are always looking for people to blame when they are losing people that do that are not responsible gamblers at all. So the best thing will be for them to budget there self when ever they are gambling.
