Yeah, every gambler's attitude in real life is mostly projected to their gambling life. there are people who ordinarily just have that addictive attitude towards everything, they overdo everything and before you know it, they are already getting addicted to it and start getting distracted by that activity. If such a person starts gambling, it will be very easier for them to get addicted. but those who mostly know how to manage every situation they find themselve and control their emotions when faced with other situations, nif they starts gambling, it'll be difficult for them to get addicted.
