I have to agree with that. And the OP mentioned lottery, you can't calculate the percentage of your luckiness in that area. Or maybe you can calculate the possibility of you winning, like 1 in a million. But how to increase your luck? I don't also believe on the his items listed. But you can change the outlook that you will put in the game.
It is difficult to calculate the percentage of the winning because it could be 50:50, but when you part in those games, the percentage will be changed, and it could be 30:70. You will not have a chance to get lucky if you cannot control yourself, being positive, and calm down, but that is not guaranteed to get or increase your luck. And sometimes, your chance to win will go to lower if you don't have good things inside the games.
