In my personal opinion I think that we don't need to focus on how much will lose and how much we own potential win. I always think that before doing gambling we should know our afford zone. And then we should make a strategy and set a limit then starting gambling. In this case I think we don't need to focus and your them lose and winning.
If we focus too much on winning or losing, of course we will rush into gambling and we won't be able to apply any strategy in the games we play, because we think too much about how to win or avoid losing in the gambling we play.
Yes I agree with you, when we use a strategy in gambling and have set a limit for us to gamble I don't think we will experience big losses in the gambling we play and when we have reached the winning limit in the game we play we will of course be able to stop and enjoy the victory that we have obtained.
