He is good after losing valuable things and money he realised that gambling is not made for money. Yes he is not addicted, but I think he becomes greedy, so because of this greedy he lost money and mobile, when we control our greedy then automatically our loss in gambling will decrease. And the winning percentage will increse bit high.
It is really depends of a gambler who is playing of how addicted he was, all of us has also a percentage of being greedy, so that some of us can easily hooked in gambling. So don't use your emotions control you, so you cannot lose lots of money eventually.
It doesn't really matter, you should not even get to a situation where you bet more then you could afford to lose.
Just bet the money you got extra and you have nothing to do with.
