Yeah, specially if the gambler is really in need of money and wants it easy and fast and a shortcut to their success, when they were hooked in gambling, that's the only thing that they are thinking IMO, to win, losing seems like not a big deal to them. Aside from that,I think they started with a strong reason( failure, family problem, financial problem. etc. ) on why they keep on pushing themselves in gambling til they get addicted.
Well all of those Problems if them keep on doing gambling they will certainly all gonna realized that it is not good and if they keep on getting on the ride of the gambling they will certainly become addicted to it, losing in gambling is a big deal and if they think that it is OK then they would probably end up losing much money or worst all of it!
