yeah right, if you have control and good management of the amount that you are willing to spare it saves you a lot, including that fear of losing your money, logically if you use spare then you can let it go and move forward, unlike with using money which is not allotted to your gambling that fear will keep bothering you and most of the time lead you to make wrong decision and lose a lot.
Yes, that's probably one of the most important things to consider when gambling.
When you are gambling with money that you don't really need, then it is all fun and games. But the moment you start gambling with money that you need for other purposes, then that becomes very stressful, as the odds are against the gambler, so that means the most probable scenario is that the gambler will lose that money.
Bad things can happen after that...
