I have met various personalities and few of them guided me on how to win in gambling. Those guys told me that "If you have got a winning mindset with no negativity in your mind, you are about to start a journey where you will see higher chances of winning over losing."

Is it like meditation where you must focus on your goal and make yourself prepared for the game before starting to play it? I had good experiences till now while following this strategy. It doesn't mean I never lose but chances of winning are really high.
