It is the gambler's problem if he's got a tough character when he can't adjust even if he's the one in need. In need of loan and in need of someone to be there for him.
That's the hard thing nowadays when you're in need and you cannot adjust your attitude and you're the one having trouble to your own life. And when your friends give you advises on what you must do to have a good ending, you will not like them because you'll justify that you are living your life in your own.
Yes, because of his tough nature, he thinks that he is good at managing himself in gambling and he also feels that he is the right one and doesn't need other people's help in any form.
And it's true what you said, this is something that is very difficult to improve in the form of better self-control because people like this are not easily given good advice, in fact they just ignore it and think that good advice is just nonsense.
If we meet someone like this, it's better to keep quiet and see how long it takes for him to realize that he will immediately stop the selfishness within him and let him realize his bad behavior himself.
They will have to swallow the hardest pill because soon they will come to realize that no man is an island, and they need someone's help.
With that, they will humble themselves to the friends that haven't tolerated them but instead given an advice on how they should deal with their addiction.
And saying that taking a loan for gambling is never been a good thing and it only going to cause more problems to their personal lives.
