If you have better limit on how much to lose, I dont think your emotion will change that much.
I cant deny that I was like you when I was still in my early gambling journey, luckily experiences teach me a lot and I can learn from it.
In gambling, having a better limit or percentage of bankroll to gamble isn't what matters above emotions rather you need better emotion to be able to manage whatever decision that you have made about your gambling habit or how much you want to be gambling from your bankroll so that at the time you get to that mark then you have the emotional control to stop.
In other words, emotion come before your gambling limit. A good gambling limit or percentage with a wrong or bad emotion will end you up so shaky. You need better control of your emotion so that you can follow your gambling plans just as when you are still uninfluenced by your gambling winnings or loses.
