Some of what you say here is true but that doesnt mean gambling will ruin your life. If you have an addictive personality and cannot control when to stop gambling, then yes you prob shouldnt gamble. If you have self control and just wanna toss a few dollars around here n there then youll be fine.
Indeed right, the only problem is those people who are highly addictive on gambling and not just gambling itself. Because if you do have self-discipline about this thing, then you shouldn't worry about being broke or something that may cause harm on your family, but, if you are a gambling addict, then, it is better if you will quit gambling before it is too late.
