We often think, deep down, that we can control how we win. No matter how many proof we are presented with that the casino always wins we always think that we can overthrow this theory that applies to everyone. Then it gets justified when we actually win so we will continue playing thinking we can actually decide when to win.
If you get statistical and logical, you will remove these thoughts and you will not become overconfident or superstitious.
Thinking we can control our winning in gambling is crazy because gambling in it self is filled with too many uncertainty so how do you hope to control something that is uncertain that you do not even know the outcome, the casino has an advantage that we cannot beat some times so it is mostly by luck you get some winnings, if you are realistic enough it will always occur to you that you are just trying your best and hoping to be lucky.
