Yeah, you need to understand that gambling is a risky activity and you needed to work on it to make sure that you are still dominant in terms of emotional control, once your emotions dominate you the risk is high for you to lose a lot and become addicted, you must be ready in quitting your way if you already lose the amount that you allocate for your gambling and not to allow your emotion to add more in trying to recover your loses.
Indecision makes it looks that way because they wouldn't be that relying or sticking to their decisions based on their initial statements of not going above their previous limits but when they senses a winning coming without thoroughly verifying that winning you would see them going to make additional deposit, just to continue gambling at this point they aren't standing on their decision that they had made earlier.
