I initially did not have the discipline to gamble, but after I experienced something that I thought was big enough to make me aware and finally made me have to stick to the discipline in gambling so that unwanted things don't happen.
For me to Acquire the discipline it was because I lost a lot of money at one point, and I told myself no more, that I Couldn't play if I Couldn't even have the discipline to demand from myself when I had to, that in the long run that was going to hurt Me, so in view of all that I did learn, ut not in the best way, hopefully some players do have the discipline to be able to say I'm not playing Anymore at the right time.
