The impact of time can make us impulsive gamblers who gamble uncontrollably and that can lead to gambling addiction. It is better when in a bad emotion to take a break from gambling and choose to gamble again at a later time, it is much more recommended because emotions can be more stable and make us think more wisely about various possibilities and minimize not making impulsive decisions which have the potential to harm us.
