What I took away from this experience is how the mentality of gamblers can change after a win. The thrill of success often leaves us wanting more and in this case it seemed like my friend was caught in that cycle, as I was feeling before too and he was unable to honor his word probably because he wanted to keep increasing his gains and bet more. It's a reminder that the brain is never truly satisfied when gambling, there's always the desire for more. I believe that friend deserves an advice, but I don’t want to embarrass him myself, is there a good way to talk to him without making him feel that Im indirectly asking him for the money he promised me?
The decisions of promising and fulfilling it in the case of gambling isn't an easy one because as the thoughts of doubling your money and getting more wins is been sinked in the minds of the gamblers and they'll always forget they have made such agreement in the first place. Well this is a normal process for every gambler usually when they are getting started to be involved in gambling habits and all they'll always think of is making a while lot which is a bad mindset and thus it's hard to control such emotions at the early stage cause the first impression of winning is what they are working with now.
