With that mentality is very difficult not just to gamble responsibly but actually to do anything in life other than failing over and over until a decision to take the reins of your life is taken. Some people have traumas and problems and it is much more difficult for them to self-control and to be self-aware of what they are doing. But I would say most people are either unwilling to progress or to lazy to do so.
That last statement, either unwilling or lazy to do so, I agree to that point, there are many gamblers who thinks that they are still in control and thinking that they are still doing the right thing, not realizing that they are already engage too much, and they can't stop playing even they already losing a lot.
You need to have that strong will to quit away or to control your involvement with gambling, if you really wanted to stop or lessen your
participation and possible losses.
