Self-control is certainly not less important. Not everyone can control themselves in gambling. That is why we often see some gamblers gambling with money that they cannot afford to lose and at some point they regret losing their money. Gambling is a game based entirely on luck where the number of losses is more than the number of wins. A gambler should lose before gambling, which should be done carefully. Whatever the result, gambling should be accepted only as entertainment or fun so that no one considers gambling as a source of income. Gamblers who are excessively greedy in gambling increase their bet amount, sometimes it gives them big wins, but most of the time they lose.
Self control is important because that can handle us with care and always aware with the situation. We will not force ourselves by playing gambling excessively because we don't want to experience big lose. We can not let ourselves like other gamblers who lose too much money because we have that experience before and know how it feel. We don't want to place a big bet in a row as that can make us lose big if we don't have luck so we will always manage our budget to place the bet. Gamblers can face losing their money anytime but we have the opportunity to control the amount of money that we can spend. That is why we always use gambling as a fun thing and not greedy chasing the big winning because that will be difficult for us.
