While gambling my instincts are mostly wrong. I am speaking from the aspect of a slot player. My instincts is just my emotions that wants me to win. In fact I don't trust my instincts. I follow the plan I have which is usually, deposit $50 - $70, pick my favourite slot game, do my spins, if I win, I withdraw my winnings. And If I lose, I try another day. I think that instincts come into play for games of skills rather than games of luck. Games where you have to really do your own homework, research, and put in your own efforts. That is where instincts may work.
Well said I would like to agree with you on this point, maybe where the skills are workout for winning for getting profit maybe on those sectors the instincts of us may work. Rather than in case of gambling, I don't think it will workout.
Even then from my experience, I never get good back whenever I got influenced by my instinct. And so I think we should think logically without believing in these things, like you said, I think we should keep a specific amount dedicated for every gambling and when that limit is over, we will take a break from gambling like that day, and on the other hand, we should set a specific target for the winning amount like 2x, 1.5x or more.
