All of us here are theoretically prepared people to not become addicted to gambling and stubbornly resist any temptation to turn gambling into earnings. Because I, like you, believe that it will not work. All those who are in the black from gambling are either strong analysts who have achieved success in poker or good sports analysts who are excellent at placing bets. But such people are 1 percent, and even then it may be even less.
Being a responsible gambler depends on your character, and on that depends whether it is easy or difficult for you to be responsible or not.
As i always say, if you don't fall into this addiction there are other insidious and subtle ones, the important thing is not to let yourself be dominated and keep everything under emotional control
That's actually the hard part of it. The emotional control. If you are in a position where you have lost too much, the mentality is to get back what you had lost and get the revenge that you want. This kind of emotion is not easy to control because we are thinking that we are being treated unfairly.
A responsible player will stop at that point and maybe just call it a day. Better, he won't be back anymore because he felt cheated. But those who have so much pessimistic lingering in their mind will keep coming back to get their revenge.
