What really makes a gambler lose? Is it greed? Well it is the illusion of control. Illusion of control leads to continued gambling and the more a gambler plays the more the casinos win, right? As a gambler, you should be able to identify these illusions so you can at least get a hold of yourself.
We often think, deep down, that we can control how we win. No matter how many proof we are presented with that the casino always wins we always think that we can overthrow this theory that applies to everyone. Then it gets justified when we actually win so we will continue playing thinking we can actually decide when to win.
Good point however it is not just greed it is just old-fashioned brain hiccups. Engineered near misses, gamblers fallacy, hot hand & illusion of control all encourage you to keep shooting wtf. also as you play more your results get closer to the house edge, math is always bigger than mojo. i have seen most pro gambler fall into these biases, though knowing others stories helps. so I always treat wins as variance rather than evidence that I am unique & I always pre-set stop-loss/time caps, which destroy systems. If you failed to do that, you are nailed by the long-term loss expectation, lol.
