You must engage in realism. Absolute 100% lack of attitude with the physical adherence to realism during the situation you are engaged in.
After years of play, discussion, study and debate, I would have to list the four most important things to be conscious of, practice and totally engaging in, when you are gaming.
1) Emotional = Complete neutralism but positiveness to enter into parlay progressions through readiness caused by confidence, camaraderie and related happenings.
2) M.M.M. = You must have a MMM that will benefit you with visible and physical positive results when you win as well as limit your losses. Gaming is available all the time, your winning is and hopefully going to produce positive results approximately 50% of your wagers and you must be able to define, use and employ additional tactics to add advantages to your buy-in and subsequently to your bank roll.
3) Plan = Have a plan and stick with it when spot-on without deviation, but the ability to abandon when it is not profitable. Do not attempt to change, turn, convert, or believe you were were 'wronged' or that the shoe will totally pay you back in the short upcoming hands that still exist, etc.
4) Ability to Leave = You must have the complete ability without second thought or re-calculations to leave, whether winning or losing. The list is long but countless events will ruin wins, countless events will only add to the losses. Both will happen, to experienced and non-experienced players.
Quality & Substance = Stop believing the fallacy of the unspecified, undefined and 'magical', always beatable events that are supposed to be the gateway to riches. They do not exist. In other words and in reality, if whatever it is, is producing wins for you within the shoe, continue it with the limited successful wagering decisions and acknowledgment of same, EVERY SINGLE HAND. If you do not, you will lose.
Ego & Attitude = We all have those two, no matter if you are aware of yours or not. But I will tell you something, from experience it is best to check them both when you sit down at the table. No two ways about it.
I promise you, they will hurt you the highest percentage of the times. You are not playing against the other players, the dealer or even the casino. You are playing with the shoe, please understand what I have preached, and preaching and what winning sections and shoes offer.
Your Play = Wagers/Bets/Thoughts. (Yes thoughts are included as well). Must match what the shoe produces, nothing else. Anything else that you allowed to enter the picture, the process, the instant hand, etc., is additional baggage that will most likely hurt you in numerous ways. Think about it and figure out what allowed you to win. NOT what caused you to win!
