That's not the point, he's actually talking about those that find it hard to make a decision in real life that they can as well find it hard to make a decision in gamble. And surely when you can't stick to your decision it is very hard for you to succeed or cope in whatever thing you're doing. take for instance when you are giving the opportunity to make cash out, you know at this point You would be having a double thought which is. Cash out, why the other would say don't cash out, at this point you might get confused as you don't know the one you would go for, and sometimes you might be forced to make cash out and if the game eventually play then, you start regretting why you hit the cash out botton in the first place.  but if you know how to make a decision and also Stick to it you won't feel kinda way even though the game played.
