But rather than saying to anyone not to gamble of they do not have patience, it would be more important in my opinion to keep in mind and advice people not to gamble if they do not have money, spare money. I mean.
Think about it, someone with enough spare money to gamble as a hobby still have a chance to enjoy it and perhaps even pocket some money in a lucky day. Even if that person does not have enough patience.
On the other hand someone with only a couple of bucks to gamble for a whole week, I doubt that person would ever have the chance to enjoy a session and if becomes dependant on gambling, unfortunately it could be matter of time before they try to get money in any way possible.
So if you are the second person, who has maybe a $100 that he can't even afford to lose and also doesn't have patience, gambling is not for you and you better do something good for yourself with that money instead of losing it on gambling.
