You cant really just that make yourself expecting something positive because gambling is really just that random and also it will really be basing up with luck factor which this is something
that needed up for you to win.
It is a fact, with the game one should never expect something with too much Expectation, because in most cases we can lose, so that is where that logic comes from that we should never forget, first limit the money, second if we already have our money willing to lose then all we should do is bet and enjoy, and whatever the result is, enjoy it and accept it, nothing more, it is a Harmless logic.
When someone have a winning amount in his mind, he must realizes about how big his chances to win in gambling. Many people already try that but they can not win from gambling instead just lose their money and even many of them lose much money because they can not control themselves when playing gambling. That is why we can not have that winning amount in mind because that can makes us lose control and can not follow our limitation in order to prevents the big lose.
We can lose many times in gambling so that is why we must prevents the lose becoming bigger. We must not think about a winning amount in mind and only thinks about have fun in gambling so we can enjoy our time to playing gambling. Besides that, we will not playing gambling excessively because we know what is the risks for us.
