You are right that discipline and bankroll definitely help but they will not maximize your winnings in any way. You know every casino has a house edge & odd management, so your money management will never be able to overcome them, . But yes if you have a good money management it will give you a lot of variety to play & prevent your bankroll from getting nuked. What I do is always choose lower edge games & follow basic strategy. I also use a fixed monthly deposit cap & set a play time which I do not exceed. You can even use pre commitment tools if you want, they will save you from overspending & losses. Always look at your winnings as a variation never think that you are a genius that is why you won, lmao.
