Let's cut the chase and understand the power of influence. Bad influences will affect your wagering and profitability.

1).  Expectations that will prevent you from winning and might increase your losses greatly. There are plenty of expectations that players believe in, for example, believing that statistical averages will appear in their favor during the few shoes they play within a session. But there are plenty of other unrealistic expectations and you better define what they are and get rid of them;

2).  Oblivious states of mind, where as you convince yourself you can win and buy-in past initial risk capital buy-in over and over. You better come to grips with what the initial risk capital and your buy-in should be and look at it as your chance to win or call it an attempt to win and walk away;

3).  Continuously telling yourself excuses for losing hands or not wagering larger amounts on your winning hands. Very dangerous influences that will put you into a completely wrong state of mind you don't want to be in;

4).  Senseless play that only leads to grinding you down. There's no way I could define them all because we all have different expectations we believe in, therefore you better think about what grinds you down and how to avoid falling into senseless play.  If you think it doesn't happen to you, you are not ready to define it and improve your game yet;

5).  Have some type of MMM/PLAN, that you strictly adhere to, with 100% belief.

When winning, never walk away unless you used up the allocation for additional play within your MMM.

One thing I repeatedly tell myself when I get to my personal win amount and my MMM kicks in is that; "If I held onto my winnings with a plan as well as controlled my losses, I would have a hell of a lot of money that I gave back in reckless pursuit of winning more". I consciously say that during most all sessions when I get into the win status, when I do. 

Remember, you are responding to what you cannot control. Meaning you're facing a shoe that will produce anything and everything and not adhere to anything you believe in or not and in random order. Therefore results will affect your inner thoughts, with or without your conscious permission. Remember that while at the table!

MMM is not bet selection, such as 1-1-1-2-2-3, or wagering on any number of triggers, etc., etc. Those are bet selection and wagering beliefs. not MMM.

A true MMM Plan, is a solid concrete method that will dictate what to do with your winnings as well as limiting your play when you lose. Period. It also can allocate larger clump wagering with a certain portion of your winnings giving you an advantage, especially with positive progressions allowing you quick profitability in much larger amounts, that most do not engage in or find it difficult to. 

Think and think hard about what I am bringing forward here.
