We don't have to spend a long hours playing.
If we gamble for fun, it shouldn't spend too much time. When we gamble long hours, it is no longer for fun. We must try to win big prizes if we force to play long hours. This is not good because it possible spends a lot of money and we may end up to be addicted. That's why it is important to limit the time for playing gambling.
Gambling and you're in the mood can prevent causing stress. But of course it is necessary that you're going to play with a main reason of entertaining yourself, and not to profit.
True, we only gamble when we have good mood. If we have bad mood in a certain day, it is better to skip the day. Just gamble in the next days when we have good mood again. Well, if we expect for profits, we choose trading. Gambling isn't a proper place for earning money constantly. We spend money in gambling for entertainment, and we don't expect much for the prizes because it is purely luck factor.
