Indeed right, when you still seeing balance inside your bankroll you mostly thinks that you'll capable to make things profitable unknowingly doing something that already hurting your balance to the point that you already lose everything, you keep doing that same mistake as greed mostly dominated us, hoping and aiming for big profits instead of being contented with some amount of money that you already earn,.
People who gamble to win and become a source of income are thinking wrongly and need to be corrected. I'm not a gambling addict so I don't know how to be greedy in gambling to get bigger wins.
I do not think they will listen because they do not need to be corrected what they need is to realize how wrong they are with the thought of gambling to earn as their primary source of income..
As long that kind of mindset is still imprinted to their minds they will never get to listen what everybody is trying to say, this is base on my own personal experience with dealing to a person which was my former co-worker in the same department who quit and resigned his job because he hit big in gambling and he tried to continue his living by doing more of the gambling work. We have not seen for a long time now but I heard he is now working again to a different company in which he again started at the bottom position.
You're right, usually no matter what advice we give them, they don't really listen because all they have in mind is their own. Been there done that, I just got tired of giving advice because everything I say that is for their good is just ignored so I just let it go, because they will learn better when they experience the things that we always say to them, then when it happens to them, they will only remember all the advice we gave them. That's why we help them so that they don't end up in such a situation, but it's their choice whether to listen or not, as long as we are kind to them.
