Gambling problem happens when you are always looking for money and looking at the gambling site as an opportunity to earn... Most gamblers disregards that but the truth is , it is what's happening, they are not there for anything else except money... Those who believe that they could earn in gambling are the ones who got into problems later on... They should wake up from that delusion before their problem gets deeper and deeper...
As quoted even with gambling when one knows to identify his situation, the problem won't go that big similar to users who go without limitations or without any targeted plan of living with a day job earning and always depends on gambling for day to day living which makes life go worse.
