i strongly believe in the Law of Attraction , when relating this to Roulette i would put the emphasis more to the wheel than to the players mood.
so lets look at trends = long run of red , black , chops , doubles , trebles , you see where i'm going with this , ok your great system suddenly starts losing so if you did the opposite you would be winning , right - the trend has changed and the law of attraction has changed with it attracting more of the same.
now the HG would be to jump on the trend change when it happens,
i know this is nothing new , i'm just saying its the "Law of Attraction" in action
