In general, it is misunderstanding that always leads a gambler to the wrong approach to gambling, maybe they think that by working harder by looking for more strategies, it will increase their chances of winning or will make them win more often than lose, when in fact it is the opposite as you said that those who work too hard in pursuing victory will actually lose more money.
The opposite will do, I mean if you stay for some wins and manage to quit after even how small your earnings, that's still a win and will prevent you from losing more, which most of the time due to greediness gambler thinks that they are lucky and they need to maximize that and will push for more.
The only problem and obstacle here is because casino games are a type of luck-based game, there is no way to beat the dealer except when you are lucky, meaning one of the reasons why they keep trying to find various strategies to get lots of wins is because it seems they don't understand that most wins depend on luck.
Yeah right, without luck most of the time the outcome is just the same, in a luck-based type of gambling, strategy unlikely to work with you not unless you are lucky and you are good in controlling yourself if you need to do a hardstop once the game gave you the chance to earn or to win decently.
But the point is that it doesn't really matter regardless of how you gamble, as long as you enjoy it then do it, but the point is one thing that you must really be able to appreciate the dedication of your involvement in gambling, such as by always being able to stop at the right time especially when you win by withdrawing it and then enjoying it for whatever you want outside of gambling, because that way at least you can feel how enjoyable the winning money is.
That's the point, enjoyment and knows how to limit yourself are still the best tools that you need when you involve yourself into gambling better to established your mindset that you are doing it in a sole purpose of entertaining yourself and not to exceed on it.
