It is known to all gamblers that once you become addicted to gambling it is impossible to quit. I have been gambling on gambling sites since many years ago and at first i was lost lot of money but later won lot of money. Personally i can say that when i deposit money in a gambling site and play the aim is to double the money so i don't worry if all the money is gone suddenly. On the other hand no one introduced me to gambling sites and i took the idea on my own research. I made myself a gambler through some articles and videos.
It's true what you say , is difficult for a gambling addict to change, but if you definitely intend to reduce gambling, you can do it , especially if you already have a family, you have to reduce your gambling.
to double the money doesn't have to be actually with gambling

Yes, that is true because the intention to stop or abandon gambling can make a person realize that he has to stop gambling. And this can be done even better if his family supports his actions because they will help him to cure his gambling addiction. His family will also accompany him through every process of healing his gambling addiction so that he will not find it difficult to go through it. But it all comes back to the gambling addict because this requires recognition that he needs help from his family, he must have a strong intention to heal himself, and he must be able to go through every healing process without complaining. All gambling addicts can cure their gambling addiction as long as they want.
